YAFT's terminfo reset should turn off sixel

[hackerb9]

Normally if one gets the terminal in a messed up state, a person can blindly type reset^J to fix the problem. This does not work in Yaft as it does not turn off sixel input when it gets a reset sequence.

For example, if someone accidentally writes a binary file to their screen and it contains the sequence ESC P, then YAFT will appear to lock up. Typing anything, even reset, has no effect.

One solution would be to add the ESC \ sequence to the terminfo reset string. However, it would be better if YAFT simply turned off Sixel input when it got the normal reset string.

By the way, in xterm, the clear screen escape sequence seems to also turn off sixel input. You can try this from the terminal:

echo $'\eP'
# now terminal appears frozen
clear             # Or press control-L
# now terminal works again

It would be nice if Yaft worked similarly.
