Configurable download clip file name

[hubunator]

Currently, if you download a clip your file gets name like this: clip_{camera_name}_{start_ts}-{end_ts}.mp4 (example: clip_MyCamera_1674735278.188583-1674735295.033573.mp4). Unfortunately, timestamps are not easy to read for humans. I would love to configure the file name format.
Example config:

events:
    file_name_format: "clip_%camera_name_%start-%end"

Example code based on https://github.com/blakeblackshear/frigate/blob/dev/frigate/http.py#L1059 :

camera_name = "MyCamera"
file_name = f"clip_%camera_name_%start-%end"
start_ts = 1674735278.188583
end_ts = 1674735295.033573

import datetime


start_dt=datetime.datetime.fromtimestamp(start_ts, tz=None)
end_dt=datetime.datetime.fromtimestamp(end_ts, tz=None)

fm_replace = [
  ("%start_ts", start_ts),
	("%end_ts", end_ts),
	("%start", start_dt),
	("%end", end_dt),
	("%camera_name", camera_name),
]

file_name = f"clip_%camera_name_%start-%end"
#file_name = current_app.frigate_config.events.file_name_format

for replace_from, replace_to in fm_replace:
    file_name = file_name.replace(replace_from, str(replace_to))

if not file_name.endswith(".mp4"):
    file_name = file_name+".mp4"



print(file_name)
