Fix actual settings (index and filename) in source

[nstwfdev]

Fix the issue when trying to access plugin settings from outside, such as in a Python script, where the data is not updated

media_source= obs.obs_get_source_by_name(MEDIA_SOURCE_NAME)

settings = obs.obs_source_get_settings(media_source)
current_media_index = obs.obs_data_get_int(settings, "current_media_index") <- never updating
current_file_name = obs.obs_data_get_string(settings, "current_file_name") <- never updating

based on my testing, current_media_index does update, so the actual fix is done in #40

the reason your fix also works is because update_current_filename_setting is also called in mps_update, but calling mps_update does too much

Please verify that my fix works on your side. I tried using the script you gave and it worked as expected
