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

The capture_cpr argument is a nice addition, thanks 🎉

I will release soon, but need to first release jquast/wcwidth#213 and then I will include #368 with it in this next release

This is released in blessed 1.39 https://blessed.readthedocs.io/en/latest/history.html#version-history

introduced: Keystroke of name CPR_RESPONSE for asynchronous capture of Cursor Position Report responses via inkey(). New argument capture_cpr=True resolves the legacy F3 key ambiguity and matches against CPR_RESPONSE. New properties cpr_yx and cpr_xy return the decoded cursor coordinates. PR #369.
