chore(npm packages): remove test files and tsconfig.json from npm tar…

[jgravois]

…balls

since we are distributing built types, UMDs, ES6 modules (with types) and common JS modules for node, it seems safe to remove the tsconfig.json entirely, especially since its incomplete.

there's no need to specify "README.md" or "package.json" or whatever is listed as "main". they are always included. this change drops the tests too to further shrink the bundles.

this will also solve problems like unintentionally shipping cruft like this:
https://unpkg.com/@esri/arcgis-rest-request@1.0.3/.rpt2_cache/

AFFECTS PACKAGES:
@esri/arcgis-rest-auth
@esri/arcgis-rest-common-types
@esri/arcgis-rest-feature-service
@esri/arcgis-rest-geocoder
@esri/arcgis-rest-groups
@esri/arcgis-rest-items
@esri/arcgis-rest-request

ISSUES CLOSED: #132

@jgravois do we even need the src/** files?

Coverage remained the same at 100.0% when pulling 37940e7 on patch132 into 2a30d22 on master.

do we even need the src/** files?

good question.

@JeffJacobson (or any other TypeScript developer), is it sufficient when a lib you depend on only exposes ES6 modules and types and doesn't include raw .ts files?

I am far from a "TypeScript developer", but, FWIW, I have been including them in other TS projects like esri-loader, but I think that's a mistake.

I'm almost certain that they are not needed because main, module, types, browser etc all point to files under dist, the only way a consuming TS app could access the src files would be import { request } from './node_modules/@esri/arcgis-rest-request/src/request.ts, and even then unless they were using the same tsconfig as us, they could have compile errors.

I say we drop src too. If we do, I'll plan to do the same in esri-loader and my other TS packages.

@jgravois TypeScript uses the files under dist like @tomwayson said. This is why we publish all the .d.ts files in the esm folder.

I say we drop /src

done and done.
