Updated caminfo default values for maxemission and maxincidence. (#4671)

### Changed

- Disabled SURF algorithm for findfeatures, latest version of opencv no longer provides SURF as part of the base library [#3885](https://github.com/USGS-Astrogeology/ISIS3/issues/3885)

- Changed caminfo's parameter default values for MAXEMISSION and MAXINCIDENCE to be

synchronized with footprintinit default values of the same parameters.

This corrects inconsistencies of footprint generation failing in caminfo

but passing in footprintinit. [#4651](https://github.com/USGS-Astrogeology/ISIS3/issues/4651).

### Added

- Added the USECAMSTATSTBL option to caminfo. This allows caminfo to extract existing

      Updated caminfo to output all CameraStatistics Keywords when running CAMSTATS.

                Specifies the maximum emission angle that a polygon point is

                allowed to have.  This limit is useful for eliminating limb data

                that cause numerous ragged spikes.  Limb data will generally

                result in odd polygon footprints as the geometry becomes

                unstable at the limb due to obliqueness particularly when using

                a DEM for the shape model (see spiceinit).  This parameter

                restricts the emission angle to create better behaved polygons

                at the limb while sacrificing some (very oblique) data.

                allowed to have.

                Note: If needing to eliminate limb data

                that cause numerous ragged spikes, set MAXEMISSION=89.5.

            Specifies the maximum incidence angle that a polygon point is

            allowed to have.  This limit is useful for eliminating

            terminator data that will typically be lost in photometric

            corrections.  This parameter restricts the incidence angle to

            create more data relevant polygons at the terminator while

            sacrificing some (non-photometric) data.

            allowed to have.

            Note: if needing to eliminate terminator data that will typically

            be lost in photometric corrections, set MAXINCIDENCE=120.0.

            Setting this parameter to 120.0 restricts the incidence angle to

            create more data relevant polygons at the terminator while sacrificing some

            (non-photometric) data.
