BUG: Tiff compression was broken and untested

A user reported receiving the error:
JPEGLib: Bogus input colorspace.
while trying to use JPEG compression witk TIFFImagio.

This was not covered and apparently never tested.

This patch fixes the erro and adds tests for each compresion option
for grayscales and RGB imagaes.

Also, a Warning message is substitued for a Debug message if LZW
compression is selected.
