Analyze test failures from datagen fixes

[niloc132]

Changes made to io.deephaven.engine.testutil.generator.FloatGenerator and io.deephaven.engine.testutil.generator.DoubleGenerator which correct range issues, effectively reduce the range of possible values. This ends up failing a variety of tests (this may not be a complete list since the generation of data isn't deterministic)

1212 tests completed, 22 failed

A commit has been made which reduces the range of the generated data in a few places - could just as easily increase the tolerance of the tests. Some investigation should be done to verify that these reduced ranges/tolerances are appropriate.
