Reduce requirements for interpolation, bias correction & outlier removal

[ayushpatnaikgit]

We weren't cleaning pixels with more than 50% missing values. I propose reducing this constraint to 90%.

Some functions like fit(SmoothingSpline, ... ) may not work with too many missing observations. We will need to test this by creating artificial missing values.
