Unmaintained and buggy (especially with ST4) + an alternative #786

This package hasn't been properly maintained for a long time and doesn't look like Microsoft wants to put any resources on it apart from occasionally bumping the typescript dependencies and tweaking the syntax.

The current issues known to me (at least when using ST4) are:

• comes with a Typescript syntax while ST4 has now a built-in syntax that is of much higher quality and should be used instead
• has issue with completions being triggered at wrong times (like after semicolon) (Autocomplete always appears after semicolon #776) (Unexpected behaviour of auto complete suggestion window. #773)
• has issues with synchronizing document state resulting in the diagnostics getting out of sync sometimes and other issues (Plugin state is out of sync after few minutes of usage #761)
• does not use utf-16 encoding (API available since ST4) when communicating with the server resulting also in synchronization issues
• overrides built-in keybindings which is a very bad practice (Plugin blocks Alt+, #736)
• known performance issues (Plugin slows down Sublime Text #716) (High CPU usage caused with Sublime Text 3 #654) (Poor performance overall #317)
• Doesn't take advantage of new features introduced in ST4 (improvements to completions handling, ability to do partial document updates) resulting in poor experience and lower performance

Due to providing generally a poor experience for the users, the ST community has decided to restrict availability of this package to ST3 (sublimehq/package_control_channel#8479) as the quality of this very popular package can heavily influence how people see ST as an editor and think that it is just worse editor than the "competition".

Note that there exists a much better alternative to this package which is the generic https://packagecontrol.io/packages/LSP package in combination with the https://packagecontrol.io/packages/LSP-typescript helper package. It's actively maintained, supports all new functionality of ST4 and is performant so that is the recommended way to go forward.

Assuming that there is not gonna be any effort put into fixing those issues, it would be appreciated if the package also mentioned that it's deprecated for ST4 and maybe suggest the alternative.
