This change adds a median filter that can replace the
IIR filter that is currently used to estimate the
avg frame size (in bytes). It is enabled through a boolean,
and reuses the window length from the max percentile filter.
The median filter is only used by the delay calculation in
`CalculateEstimate()`. It does not replaced the use of the
IIR estimate in the size outlier rejection heuristic.

This change adds a percentile filter that can replace the
"non-linear IIR" filter that is currently used to estimate the
max frame size (in bytes). The percentile filter is enabled through
the field trial, and it has two tuning parameters: the percentile
that is deemed the "max" frame, and the window length over which
the filter is applied.

The constants are reordered to match the order they are used
when a sample is inserted into the filter. Some of the constants
are renamed to better describe their usage. No functional changes
are intended. Future CLs will add configurability to some of these
constants.
Some basic unit tests are also added.
