parselib handling 'other' chunks incorrectly

[jbeta51]

Android version(s): all
Android device(s): all
Oboe version: 1.4.3

Short description
The wav reader will crash when asked to parse a wav file with a chunk type other than RIFF, fmt, or data. In the 'else' branch, we want to skip the contents of 'chunk', but we instead try to access the length of mDataChunk, which is null before hitting the data tag.

Steps to reproduce
Create a meminputstream with a wav file that contains a chunk type such as 'LIST'

Expected behavior
The LIST chunk gets parsed and skipped.

Actual behavior
When trying to skip the chunk, it dereferences the wrong chunk throwing an error.

Device
All
