Avoid checking floating point values for equality

[NamelessOne91]

Avoid a floating point values equality check in TestJunit::test_get_totals.

We have noticed the following failing test in #30

FAILED test/test_junit.py::TestJunit::test_get_totals - AssertionError: {'fai[29 chars]ped': 0, 'passed': 63, 'tests': 66, 'time': 1334.5865919999999} != {'fai[29 chars]ped': 0, 'passed': 63, 'tests': 66, 'time': 1334.586592}
  {'errors': 0,
   'failures': 3,
   'passed': 63,
   'skipped': 0,
   'tests': 66,

?                    ^^^^^^^^

+  'time': 1334.586592}

Looks like to be just a rounding difference due to floating point precision.
As that is often time dependent on architectures, programming languages etc it might be better to remove the equality check altogether and just check that the 2 values are really close

Thank you very much, Paolo, for taking a look so quickly and providing a fix.

TIL about isclose. Nice fix!
