DLL was able to be analyzed.

The program converted from IR code to the code of
which Pronto used with XML was made.
Separately, DLL of ProntoEdit NG is necessary.

Execution example:
>prontoir "900A 006D 0000 0001 18E6 00FF"
58 0 f 6c 5 60 ab 16 15 40 ab 55 3f 7f f0 b 31 10 10 10 20 20 10
10 10 10 20 20 10 10 20 20 20 10 10 10 10 10 10 10 10 20 20 20
20 20 20 20 20 0 bf 49 f0 a bf 10 4 f0 d

I think that it can efficiently analyze it by using
this though it seems to take time.
I will try the analysis of the code when there is time
because it was able to achieve my purpose by this.
