9c6c0c01ae
Adds TGA 2.0 compliance: - Support for Extension Area, Developer Area and Footer (metadata support) - Support for 15-bit and 16-bit per pixel images (both RGB and Indexed) - Full support for rotation on reading (we cannot use Qt transformations because only a subset is part of the TGA specification) - When writing you can choose the supported version (subType) - Improved writing speed (approximately 10 times) and removed whole image conversions (significant memory savings) It pass the [TrueVision TGA 2.0 conformance suite](https://github.com/zigimg/test-suite/tree/master/fixtures/tga). Test changes: - Read test: added ability to skip a specific test on sequential devices (via JSON behavior file) - Write test: added the ability to set the subType when writing (via JSON properties file) Closes #37
