* update to use go-storage/ instead of go-store/v2/storage/
* pull in latest version from codeberg
* remove test output 😇
* add code comments
* set the exclusive bit when creating new files in disk config
* bump to actual release version
* bump to v0.1.1 (tis a simple no-logic change)
* update readme
* only use a temporary read seeker when decoding video if required (should only be S3 now)
* use fastcopy library to use memory pooled buffers when calling TempFileSeeker()
* update to use seek call in serveFileRange()
