#223 Get in-file loop information

[SysVR]

I want you to be able to get the loop information in the file.

For example, a wav file has a smpl chunk,
https://sites.google.com/site/musicgapi/technical-documents/wav-file-format#smpl
Loop information is described in it.

Also, in most formats, the loop information is
I think that it is binary data in unencrypted frame units or block units, so
Offset binary, start offset, range binary size
End offset, end binary size, number of times offset.
In this way, it would be nice to be able to specify a value to specify the loop from the binary. (If the binary string or offset value, for example, the binary range in which the range is described is 00 00 00 00, [4bit])
