[data] stringify cutscenes.s

[rpadaki]

For this PR, I added a bunch of heuristics to the script I used for #157. This lets me find most of the strings in this file, though it's very possible that I'm missing some.

• If I see an unknown byte, I log it and assume the whole block is not a string
• If a block is less than 5 bytes, I assume it's not a string (or small enough that we can do those by hand when they come up)
• If a block ends with 5 or more null bytes, I assume it's not a string (Something something alignment? This is totally a heuristic)

The more complete charmap.txt is, the more strings I can find. The script is a little too finicky to be shared rn but I'll clean it up when I have time.

Will let #158 merge before this, per Discord convo.
