ipa: libipa: Add MatrixInterpolator class
Add a class to encapsulate the functionality of fetching a matrix based on an integer key, and interpolating if there is no exact match. This is expected to be used by both color correction matrices / crosstalk correction as well as lens shading correction. A cache is included only for exact matches of the key. The caller is expected to decide the tolererance for rounding.
