Filelog Receiver support ingest from compressed files

[jwimmersplk]

Is your feature request related to a problem? Please describe.
Under high load, log rotation process is triggered before the Otel agent filelog receiver can consume the remaining log data.

Describe the solution you'd like
Allow the filelog receiver to read from compressed form, specifically .gz

Describe alternatives you've considered
Modifying the polling_interval and the logrotation max size configs but these solutions still leave the possibility for data loss and not realistic solutions for production workloads.
