consider allowing to specify the exact file instead of a folder that has a tsconfig.json

[zpdDG4gta8XKpMCd]

seriously, each tsconfig.json has to have its own folder in order to be referenced with --project parameter

• What if I need 2 projects based on the same set of files?

This would be really nice.

Behold, ask and ye shall receive a ~2 month old pull request from @saschanaz which incredibly has absolutely no merge conflicts right now: #4883

Also that sort of makes this a duplicate of #2869, though I'm leaving this open for the sake of discussion.

Since --project is taken already I suggest the --configuration parameter

this is a duplicate of #2869. we should revive #2869 as well as #4883
