Initial encode support
...
* Encode support for all PNG formats, interlacing for >= 8-bit
* Initial chunk write support for most standard chunks
* Fixed spng_set_text(), spng_set_bkgd()
* Added spng_encode_image(), spng_get_png_buffer(), spng_set_unknown_chunks()
* Split up spng_decoded_image_size() internally
* check_png_keyword(): add length check
* read_ihdr(): set ctx->current_chunk, cleanup
* Set default image limits in spng_ctx_new2(), not the decoder
Testing
* Added test case to verify encoding against libpng
* Encoded PNG's that fail a roundtrip test are dumped to disk
* Cleaned up test case generation
