th08 trial v0.01: files from dat appears to extract slightly corrupt

[Dobby233Liu]

For example, with title01.asm:

thdat -x8 th08tr.dat title01.anm
thanm -x8 title01.anm

data/title/title02.png will look like:

th08_00.mid similarly appears to extract corrupt, with data around the 0x2800 mark not resembling valid MIDI data (according to @\ahigerd).

(Not sure if trials are in-scope but meh. If not, would at least appreciate guidance on how to patch thtk src to work around this)

So it appears th08_crypt_params is slightly different in v0.01. Dobby233Liu@2681758

it's in scope, but we don't have a good way to support trial versions yet
