This supersedes #321. I studied kitty and xterm parsing about this small possible deviation from ECMA-48/ITU T.416/etc. standards, and those changes have been simplified (WCWIDTH_SGR_MAX_PARAMS was removed, malloc/realloc/free removed), while also supporting "hybrid" sequences found to be supported in at least xterm and kitty, and it brings coverage of the changed code up to 100%

Note that #321 was likely created by AI Analysis, that these are probably Unlikely sequences, but, because I discovered code in xterm and kitty that attempts to support them, it is presumed that some misbehaving TUI program or library somewhere must have drove them into the more complex accommodation.
