Optimize parse_line function with iterator and improved error handling

[FernanCa12]

• Replace vector with iterator for line_split, improving memory efficiency and laziness
• Simplify error handling for log_type and timestamp parsing using and_then and ok()
• Use pattern matching to simplify condition for ignoring log lines
• Maintain compatibility with functions expecting a slice of remaining elements by collecting iterator elements back into a vector

Note: Just a few change, hope they will help with something

I like the changes a lot, however my shitty parser code later access the slices by index, and this change breaks the parsing at the moment Maybe we change all to using an iterator instead of slice?

I tested using an Iterator instead of a Slice to see if it would improve performance. While there was some improvement, it was not significant enough to justify continuing with the Iterator approach. Additionally, since the data processing is relatively simple in most cases, the potential performance gain from using iterators over a vector slice is minimal.

I will proceed to close the pull request.
