BUG: ResourceProbe::Reset() should set m_MaximumValue to lowest value
BUG: ResourceProbe::Reset() should set m_MaximumValue to lowest value

Before this commit, `ResourceProbe<ValueType, MeanType>::Reset()` did assign
`DBL_MIN` (~2.2e-308) to `m_MaximumValue`, when `ValueType` = `double` (for
example, for `itk::TimeProbe`). This gave incorrect results, when all values
retrieved by `GetInstantValue()` were less than `DBL_MIN`.

This commit fixes this bug by assigning the lowest value, `NonpositiveMin()`
(instead of `min()`) to `m_MaximumValue`, within `ResourceProbe::Reset()`.
