Refactor to es6

[jankapunkt]

This pr moves all code to ES6 and removes outdated dependencies where possible.

Hey @TheRealNate @diavrank I completely updated this library and replaced lodash with native ES6

If this gets released we can update the core to use this instead of the 6 years old minimongo and have nearly all vulnerabilities removed.

@TheRealNate can you take a look at this? This is required to fix all these lodash issues that arise when install @meteorrn/core and minimongo-cache is somewhat abandoned so this is now our new updated minimongo cache with lodash replaced by native ES6.

Once this is published, for example as @meteorrn/minimongo then we can finalize the current PR on @meteorrn/core (meteorrn/meteor-react-native#99)

Looks good to me! Merge when ready

Thank you @TheRealNate can you publish it to npm? We can then include it in meteorrn/meteor-react-native#99

@jankapunkt Done. Theres a GH action setup to auto publish when a new release is declared, so you should be able to use that in the future.
