Swap ansi-escapes for a working cross-platform clear

[stramel]

This swaps out ansi-escapes which we utilized clearTerminal, for a working windows command.

The main difference is just a slight difference in the ESC sequence. This swaps, \u001B[ to \x1B[. This is how Jest and CRA both handle their clearTerminal command.

Works for me! Thanks for taking the time to dig into this, can't believe ansi-escapes doesn't handle this by default

Their code is nearly identical.

Our new output:

process.platform === 'win32' ? '\x1B[2J\x1B[0f' : '\x1B[2J\x1B[3J\x1B[H'

vs

ansi-escapes:

process.platform === 'win32' ? '\u001B[2J\u001B[0f' : '\u001B[2J\u001B[3J\u001B[H'

I brought it up in the issue that I had opened over there to see if they would be willing to update their code.
