[BUG] Duplicate lap times in source data for GRO incorrectly handled in 2020 Round 4

[theOehrly]

Describe the issue:

The source data for the 2020 Round 4 race (British GP) contains some duplicate lap times for GRO (car 8) around lap 14 and 15.
More preicesly, the lap time for lap 14 is received again after the lap time for lap 15 was already received and the lap count had been increased. The lap time for lap 15 is then received again a few seconds later.
This should cause the correct value to be set for lap 15, but the value of the lap time for lap 15 is greater than 150 seconds and therefore ignored by the timing parser (see #473). Therefore, the value of lap 14 is used for both lap 14 and 15, resulting in a subsequent timing integrity error.

Potentially related as well: #404

Reproduce the code example:

import fastf1

session = fastf1.get_session(2020, 4, 'R')
session.load()
