What
Replaces the bufio.Scanner with bufio.Reader.ReadBytes and flushes batches. No record size can now truncate or fail an index import.
Why?
The scanner was capped at 4MB and osv's largest record is ~19MB. ReadBytes grows to fit the record, so there is no ceiling to raise again.
Notes/Testing
Inserts into the DB are still controlled. There is a 25MB flush size and a max document size of 1GB (these are existing limits and unchanged). Tested locally by syncing ~30GB of data to offline db.
Blank lines are now skipped rather than raising errors.
Adds three cases to import_test.go
