Vladimir Serbinenko b58b09323c SCUMM: Support for uncompressed bundles like used in some fan translations
Apparently it's a beta variant of storing files in the bundle without
compression and in little-endian. I tried to find an indicator for endianness
in uncompressed iMuse file but apparently there isn't any. Hence we need to
propagate a bool from bundle to imuse layer.
