Fixing sound error and errors in map rfid

[aobermiller]

Fixes #185 Fixes #186

What was changed?

Anywhere that calls AudioManager.play() had the file path of the audio file being played changed. Experiment database now has a function to changed the RFID number of an animal.

Fixed additional errors in map_rfid that were caused when removing and adding animals.

Why was it changed?

Audio was not working anywhere in the program.

There is an error when removing then adding an RFID in the map_rfid function

• Removing all animals at once resulted in the added animal_id being to large
• Added animals after the maximum number of animals was reached (even after removing an animal) led to an error where all cages and groups were full.

How was it changed?

Everywhere in the program that calls AudioManager.play() now plays from the directory "/shared/sounds/" instead of "/sounds" (see lines 130 & 220 of data_collection_ui.py and lines 152, 162, 237, and 487 of map_rfid.py

Added a new function to ExperimentDatabase which takes an animal_id and rfid number and changes the rfid number of the animal in the database to match the passed rfid number.

Changed get_next_animal id to properly find the lowest unused animal id.

Added three new functions to experiment_database (See implementation here: https://github.com/oss-slu/Mouser/blob/6e8a79116ce7bfc674c8e33cb641b8638f2052ee/databases/experiment_database.py#L193-L234).

• remove_animal removes an animal from the experiment, including from cages, groups, and rfid tables
• remove_animal_from_cage removes a single animal from a cage
• remove_animal_from_group removes a single animal from a group
