searchkit/constraints: rewrite of binary search algorithm

Implemented a new binary search algorithm that no longer needs
filemarkers or knowing the lines beforehand, which reduces the
time spent applying a SearchConstraintSearchSince to a file,
especially if the file is large in size.

Removed the following classes which are no longer necessary:

- SkipRange
- SkipRangeOverlapException
- BinarySearchState
- FileMarkers (and respective unit tests)
- SeekInfo

Removed `test_logs_since_junk_not_allow_unverifiable` test case since
we're no longer parsing all lines in the file.

Removed following functions from BinarySeekSearchBase:

- _seek_and_validate
- _check_line
- _seek_next

Introduced the following new classes:

- LogFileDateSinceOffsetSeeker (the main binary search class)
- DateSearchFailedAtOffset (exception type)
- NoLogsFoundSince (exception type)
- NoDateFoundInLogs (exception type)
