isponsorblocktv: fix

We're using different versions of dependencies, and the package is a
major version behind on textual (a TUI library - nonessential, just used
for the setup TUI; there's a setup text interface which works fine), and
pyytlounge (essential, because this wraps the YT API used).

This provides two temporary fixes that work around the problems. The
textual patch can be upstreamed; the pyytlounge patch probably won't be
since I think a more robust approach will be forthcoming from the
iSponsorBlockTV author.
