Convert to TPC

Now the TPC tool can create uncompressed TPC files given PNG inputs.

Use as many --txi="key value..." options as you like to add TXI attributes.

The TXI handling has also changed a bit. Multi-line attributes are formatted in a single line for print-outs. For example, to add a "channeltranslate" attribute add this option:

--txi="channeltranslate 4 0.1 0.2 0.3 0.4"
