Pin "pywinpty" to v0.5.7

[kaste]

pywinpty dropped support for python 3.8 but all current versions have important issues.

• After the program sends a character, it takes at least 100ms to read it andfoy/pywinpty#463
• PtyProcess is leaking conhosts andfoy/pywinpty#484
• First call of PtyProcess.spawn creates a visible terminal window stealing focus of invocating app. andfoy/pywinpty#483

I manually downgraded to test if Terminus works with the old version, and looks like it does.

Just dropping it here; I don't know if this is the correct way of doing a version freeze.

Seeing how @deathaxe already investigated this in sublimehq/sublime_text#6550, I'll leave this for him to handle.

As PC doesn't downgrade installed packages/libraries, nobody who has pywinpty dependency installed already would be affected.

Beyound loosing focus when starting a terminus session for the first time, there are no obvious negative effects besides increasing amount of conhosts sitting around.

Hence I actually don't see much value in pinning it to a decade old release.

Let's see if issue gets fixed upstream.

Currently there are no py38 incompatible changes in latest release, they just dropped creating wheels. Thats easy to fix.

The 100ms delay per keypress makes Terminus completely unusable or at least makes it feel completely broken. As a new user I think you would likely just uninstall Terminus.

Delay? In which condition? I don't see any on Win11

I had a lag between keypress and the character appearing on the screen. That was also reported on the original Terminus issue. (Very noticeable with ipython.) A search showed the 100ms issue I linked above immediately, so I stopped further investigations.
