Make pulse_id continuous in chunks

What does the code in this PR do / what does it improve?

Fix #229

And a problem with sorting of photon_pulses and pulse_ids.

In previous codes

fuse/fuse/plugins/pmt_and_daq/photon_pulses.py

Line 131 in 9baffd3

photon_pulses = strax.sort_by_time(photon_pulses)

photon_pulses is sorted before assigning photon_id to pulse_ids.

Can you briefly describe how it works?

Similar to https://github.com/XENONnT/straxen/blob/b8fe520deca55b8c5ac0cb53249b38639f0ae5de/straxen/plugins/events/events.py#L154, first make an attribute pulse_ids_seen of PulseWindow, then update it for each chunk.

Can you give a minimal working example (or illustrate with a figure)?

Please include the following if applicable:

• Update the docstring(s)
• Bump plugin version(s)
• Update the documentation
• Tests to check the (new) code is working as desired.
• Does it solve one of the GitHub open issues?
