CPR_RESPONSE and coordinate capture with inkey(capture_cpr=True)

[jquast]

Closes #367

Parse for new Keystroke of name CPR_RESPONSE and attributes cpr_yx and cpr_xy. This allows inkey() to capture the response for Cursor Position Report asynchronously.

New argument to inkey(capture_cpr=False) continues to match "legacy CSI Modifiers" for the F3 key as KEY_SHIFT_F3 et al, but, when set True, always matches as KEY_CPR_RESPONSE.

New example programs,

• bin/cpr-every-pos.py an exhaustive integration test
• bin/cpr-async.py provides an asynchronous example
