Boat Speed Boundary escape fix

[kabarmaz]

Related Issue / Discussion:

Algorithm accepts speed values out of the range of 'BOAT_SPEED_BOUNDARIES'.

Changes:

• Added statements to keep boat speed within boundaries while calculating speed with arrival time to population.py(line 116-121).

• Added a test that sets the boundaries to 6-7 and verifies the recalculated route speed stays within that range and gets clamped to upper bound when needed to test_genetic.py(line 331-333)
