Benny Siegert c35a1ecb6c go.image/tiff: use optimized routines for RGBA and NRGBA 
Performance for an RGBA image:

benchmark          old ns/op    new ns/op    delta
BenchmarkEncode      1633495         7897  -99.52%

benchmark           old MB/s     new MB/s  speedup
BenchmarkEncode        37.83      7824.96  206.85x

NRGBA images are now encoded as such, the spec calls it
"unassociated alpha".
