awpy.Demo().events dictionary sometimes missing steamids data

[ventsiR]

Describe the bug
Sometimes some entries of the awpy.Demo().events dictionary are missing steamid data. E.g. I have noticed that in inferno_startburn, the pandas dataframe is sometimes missing some values for column user_steamid.

Include Information to Reproduce
See this match for an example: https://www.hltv.org/matches/2375372/9z-vs-wildcard-esl-pro-league-season-20

Run awpy.Demo().events on the nuke game. In inferno_startburn you will find that some incendiary grenades do not have a user_steamid (i.e. a thrower) associated with them. Through watching the demo, it turns out this missing player was Sonic. Strangely, in that same demo, this does not occur with smokegrenade_detonate or other dictionary entries.

Here is another example:
