…er AMVs (#724)

**Description**
This is an update of the QC process for the enhanced high-resolution
GOES-R mesoscale floater AMVs to resolve the issue #713.
As mentioned in the issue, enhanced AMV data are derived from IR band,
which turns out to be not reliable in the mid-layer of atmosphere.
Adding additional QC process to remove data in those layers are
necessary and proved to enhance the Hurricane intensity forecast.
