[*] Refactor NoncanonicalInput
[*] Fix various keys resort in NUL getting added to ConsoleTTYs input field
[*] Fix multichar right key input (finish TODO note)
[*] Hex grammar: literals may end with 'h' now that i think about it. also added wiresharks seperator. let's continue to simply make sure we cover all forms of hex in a reasonably liberal fashion to account for user input from various human written and software form.
(Nonuniform style of non-hex illegal chars are fine so long as it looks and reads like a legal array of hex characters. Comas must come directly after literals, possible [0x] prefixes are fine, whitespaces too, copy/pasted '[', ']', '{', '}', 'reasonable' new line rejection, etc)
