Add additional QC filtering to timeseries

[mollybsmith-noaa]

Stan has requested a way to filter out points too far from the curve mean on timeseries plots. After discussing this today, it seems like there are two things we should do to address this:

• Add a new QC filter to the param selection page for timeseries. Users can select their level of SD filtering, and any points more than that range from the curve mean will be discarded after querying. This means that the final curve stats will match the curve.
• Revamp the "Filter Points" option on the graph page. It's too hard to scroll through all the x variables and find the one you want. Instead, have an event where users double click on a point to remove it from the graph. This will not update the curve stats, but is useful in diagnostics.
