Incorrect files path (does not catch all files)

[FFdhorkin]

cli.js has this line:
const files = args.filter(file => /\.(ts|tsx)$/.test(file))

This is incorrect - it doesn't support cts or mts files. It also doesn't work with js/cjs/mjs files with checkJs turned on.

Should be something like const files = args.filter(file => /\.(c|m)?(j|t)sx?$/.test(file))

My fork implemented this: https://github.com/skayo/tsc-files
Not sure if I should do a PR here since I changed some other things, but for now I'll release it as my own package (@jonasgeiler/tsc-files).
