v0.4

NOTE: Hero 13 Black compatibility is unknown until I get hold of sample files (it once again has a GPS module)
BREAKING: Methods for locating/grouping files in recording session now return Result with optional "skip on error".
NEW: determining high/low resolution clip no longer depends on file-extension, only resolution, where 1920 x 1080 is used as the minimum for determining whether a clip is high-resolution (.MP4) or low-resolution (.LRV).
FIX: Fixed overlapping timestamps when merging GPMF data from multiple MP4-files

v0.3.1
