v0.5.4

Fixes type tree reads of one-byte char vectors, HDR ASTC void-extent rounding and the names of Cubism expression blend modes. Recommended for everyone on 0.5.x.

Fixed

• Read a type tree char at its declared byte size. Unity's engine trees declare char as one byte, so vector<char> fields such as Font.m_FontData, AudioMixer name buffers and BlobObject.m_BlobData were read as two bytes per element and failed with "failed to fill whole buffer". Caller-supplied schemas and two-byte char keep the two-byte read, and any other size is refused as invalid data. (#28) by @nichinichisou0609
• Round HDR ASTC void-extent blocks to the nearest level, as astcenc does, instead of truncating. LDR output is unchanged. (#29) by @nichinichisou0609
• Report Cubism expression blend modes under the right name. Ordinals 0, 1 and 2 now map to Overwrite, Add and Multiply as in the Cubism SDK for Unity; before, every mode was misnamed. The Python CubismExpressionParameter.blend strings change for the same input, while exp3.json bytes stay the same. (#30) by @nichinichisou0609
