don't garble partial multi-byte character after control sequence
When use [lf](https://github.com/gokcehan/lf) to list files, emacs-libvterm may
read partial multi-byte character, for example:
$ echo -n '招聘' | hexdump -C
00000000 e6 8b 9b e8 81 98
; get "招", control sequence and partial character
(vterm--filter process "\xE6\x8B\x9B\e[14;111H\xE8")
; now full "聘"
(vterm--filter process "\x81\x98")
This will send "\xE8" to libvterm which is not a full character.
