Research way to expose time filtering for UnifiedLogs

[puffyCid]

Currently this library does not support native time based filtering. Right now in order to filter by time the user would need to import the library and parse each log entry and filter on each entry.

It should be possible to make time filtering faster. Based on my current notes the tracev3 header and timesync files should expose enough info to implement faster time filtering.

It may be possible to implement faster time filtering by just updating the example binary and adding the feature.
Otherwise the library may need to be updated a bit to ensure enough info is exposed to implement time filtering for users who import the library

I think it would be better for filtering to be in the example binary only yes. It'll keep the featureset of both the library and example clearly demarcated: library just for parsing, the example binary for processing and transformation of data.

Let me know what the exact featureset should be and I'll work on a PR.
