Store metadata in the record file

[oberien]

Currently the record file contains a list of RecordFrames, each of which contains:

• delta time
• input events
• location
• rotation
• velocity
• acceleration

In addition, we should put metadata next to the frame-data-list. Therefore, instead of saving a list, a struct containing the name and the list should be stored. Metadata might be (list not complete):

• player name
• timestamp of recording start
• timestamp of recording end
• timestamp of saving
• filename the recording was saved as
• max character speed
• playercontroller base speed
• playercontroller max base speed

Steps:

• add a new external struct in rebo_init.rs next to the RecordFrame, which contains the metadata as fields and the list of frames also as a field (don't forget to add the external type to rebo)
• take the new struct as argument in save_replay and return the new struct from load_replay • build refunct-tas to get the latest refunct-tas.exe and rtil.dll • change rebo to use the new struct everywhere
