[farfromrefug]

This PR add many things which improve typings generation:

• improved PR https://github.com/NativeScript/android-dts-generator/pull/85, fixing bugs and adding more edge cases
• handle kotlin parameters without return paramter names with forbidden chars
• ensure replaceGenericsInText does not remove > chars far already any types
• better detection of open/close namespace to prevent unclosed namespaces
• some inner namespaces where not correctly filled/exported
• kotlin Companion is now a namespace making static functions being reported correctly
• add eslint rules at the top to prevent vscode errors
• constant values real value is now exported as jsdoc. Using direct values was failing in some cases and vscode was reporting errors
• a new flag -per-library which will generate separated files for libraries. Also the name contains the library name/version which makes it easier to maintain typings
