Enhanced version

[ForceBru]

What's new:

• Improved user interface: now uses command line arguments via argparse, waits until user plugs in iDevice, checks iDevice name until device is recognised by iTunes
• Checks generator correctness as indicated in the original Reddit post
• Better parsing of subprograms output with regexes
• Better error reporting
• For developers: included binaries of idevice_id, ideviceenterrecovery, igetnonce, irecovery and tsschecker for x86-64 Darwin, also added links to original repos in README

Requires Python 3.6+ mainly because of f-strings and the encoding parameter of subprocess.run.
