* created new decoder and encoder for PFM pfm file format stores binary RGB or grayscale float images. * added test for pfm codec * replaced large with short licence header * little/big-endian-check is now compile time * fixed width/height confusion, improved big/little endian recognition, fixed scaling issue and Improved signature check * adapted tests to handle float images well * removed data-dependency: lena.pfm the lena image is now loaded is pam and converted to pfm. * fixed bug in endianess detection macro * Added endianess detection for android and win * removed fancy endianess detection endianess detection will be implemented in cmake scripts soonish. * fixed minor warnings * fixed stupid elif defined bug * silenced some implicit cast warnings * replaced std::to_string with std::stringstream solution std::to_string variant did not build on android. * replaced new endianess macros with existing ones * improved readability
