feat: 0.9.0 (#196)

## Refactor
* refactor(internal): renamed memorised ids name  in factory
  * This will reduce the likelihood of clashing with user's code

## Performance
* perf(internal): removed repeated calls in factory builder `getKey` method

## Fix
* fix(internal): prevent losing error name when mangling code
* fix(factory): ensured states are only called once
* fix(model)!: `exists` now accepts any string id as valid
    * So long the string has length
* fix(factory)!: factory now respects the model's key type
* fix(attributes)!: recursively transform keys on mass-assignment
    * On outgoing object keys were recursively set back to `serverAttributeCasing`.
    * Now the incoming object keys behave the same way and are set to `attributeCasing`.
    * Bringing it the behaviour in line with expectations.
* fix(attributes): added SimpleAttributes type
    * This type is same as Attributes except it does not include Models and ModelCollections
      Resolves #183
* fix(timestamps): added missing deletedAt value in FormData
* fix(attributes)!: updated attributeCasing modifier type to protected
    * just like `serverAttributeCasing` this isn't expected to be used outside of the class.
* fix(model-collection): fixed `toJSON` return type
    * Type information got lost when using return type of model type argument's `toJSON`

## Feature
* feat(factory): added factory type argument to factory builder
* feat(model): added keyType getter
    * This change allows for custom string ids that are not uuids and the factory to set keys as string
* feat(model): improved `getKey` typing
    * It now returns the correct type based on the type argument or `keyType` return value
* feat(model-collection): improved `modelKeys` return value
    * Changes missed from 6c54090
* feat(api-calls): improved `call` method signature with overrides
* feat(attributes): added `RawAttributes` type
    * This utility type helps describe the raw json version of the model.
* feat(factory): improved raw method typings
* feat(factory): added `attributes` method
* feat(collection): added missing array methods
* feat(factory): added missing type export
    * Missed in 5c191a2
* feat: added `PartialSome` utility type

## Documentation
* docs(factory): give more helpful error messages in case of mangling
* docs(factory): added tip for factory files and improved interface doc
* docs(model): updated examples to use `create`
    * Missed updating when moved to the `create` method
* docs(model): updated documentation around mass assignment
* docs: simplified custom collection extending recipe
* docs(api-calls): fixed wording
* docs(attributes): formatted inline comment
* docs(timestamps): added comment

## Testing
* test(factory): added test for states application order
* test: improved test helpers
* test(model-collection): fixed typing error in test
* test(factory): reset state after testing
* test(attributes): corrected test block name

## Chore
* chore: incremented version
* chore: updated test tsconfig
* chore: removed unused type import
* chore(deps-dev): updated dependencies
    * @commitlint/config-conventional
    * @commitlint/prompt-cli
    * @commitlint/types
    * @typescript-eslint/eslint-plugin
    * @typescript-eslint/parser
    * commitlint
    * eslint
    * lint-staged
    * rollup

## Continuous Integration
* ci: ensure `.nojekyll` exists

## Refactor
* refactor(api-calls): `customHeaders` type DRY-ed by adding a type

## Style
* style: fixed code style issues
