fix: handling existing file when starting recording

[vkornel97]

Description & motivation

This PR introduces a fix to prevent potential errors when starting a new recording with HKStreamRecorder. Previously, attempting to record with a file name that already existed in the destination directory would cause an error, as AVAssetWriter fails if a file already exists at the specified path. This fix ensures that any existing file with the specified name is removed before the recording process begins.

Type of change

• Bug fix (non-breaking change which fixes an issue)

Recording of live streams is valuable. It’s not desirable to delete it automatically.
In this case, an exception should be raised, allowing library users to handle it themselves.

There are a few parts I’d like to revise, so I’ll take care of it on my end.
