Subject: refactor: Another small optimization pass (#350)

Making some small changes that would hopefully improve performance a bit.

- Remove redundant string generations for CPU data conversion
- Switch to fnv for PID hashmap and hashsets
- Use buffered reading to avoid having to store too many lines as strings
