fix the frames of cua and fea

[mi2ebi]

from c ci 1i to c c 1i. i don't personally like either of their definitions but we can address that later or never

[mi2ebi]

i've also fixed buja (which had an e slot), and chia and dui and ko (which had two non-c slots). new-ko (c c c 1x), koe (c c c 2ij), and teq (c c c 1k) aren't changed beyond that since their definitions still have 4 slots and those frames are all valid if we accept that (though again we could fix the definitions later)

[mi2ebi]

(so now those are the only three entries where the frames don't match the [whitespace-insensitive] regex

^
(0
|1x?
|2(xx)?
|c(0
  |1[ix]?
  |2([ix]{2})?
  |c(0
    |1[ijx]?
    |2([ijx]{2})?
    |c
    )?
  )?

Looks uncontroversial to me.
