write rawfiles (single file) and read rawfiles in order (#66)
* read subfiles with unordered and missing frames

* save work debugging

* Revert "save work debugging"

This reverts commit e791992a05efd754f93a80c980d17397eb4b6045.

* Revert "read subfiles with unordered and missing frames"

This reverts commit 1177fd129d3690db92e9597ccda62598e5a44d41.

* throw when two frames have different frame numbers

* write single part RawFile (working beta)

* correct total number of frames in master file

* add new mythen file with syncd frames

* read frames with same frame number

* clang-tidy fixes, formatting, add tests

* improve readability in loop

* fix failing tests
