Subject: [PATCH] Fix read_resource returning empty bytes for uncompressed
 resources

When sizeField's low 30 bits are 0 the resource is stored uncompressed
(dsz bytes on disk, still XOR-scrambled when bit31 is set), but
read_resource passed comp=0 to f.read() and returned 0 bytes.
TEXT/TEXD resources are stored this way in both retail chunks.
