Deprecating TsProject in favour of gulp-ts-bundler

[ToddThomson]

TsProject release 4.0.0, supporting Typescript 4.0, primarily served as a single typescript module bundler for gulp as a vinyl file adaptor. It included a Typescript compiler, a module bundler with a single dts file, and a minifier all in a single library package.

With release 4.1, TsProject will break out the compiler to Ts2Js; the bundler to TsBundler and the minifier to TsMinifier. Much of this work was done years back, but I never had time to complete the task.

So what to do with TsProject? I feel that it should continue to be a gulp plugin vinyl adaptor and just utilize the other component packages as dependencies. It should be renamed to gulp-ts-bundler. This name change would better reflect what the package does and is.
