Enhancement: linear interpolation

[agmeiner-bhs]

Hello,

thanks for this great package.

It would be very useful if a linear interpolation for NA values were possible in the collapse package. The range of functions here could be based on zoo na.approx() or na_interpolate() from imputeTS. But even if there were only a basic functionality, this would be extremely helpful.

Thanks, I’ll consider it, but can’t promise at this point.
