NEAR/MSI msi2isis and MsiCamera model improvements

[KrisBecker]

Description
The msi2isis and MsiCamera model have been improved to support development of new global color maps of Eros. These modifications are included in the forthcoming PR.

We have produced a new set of NEAR/MSI Eros images where the remediation of hydrazine contamination has been improved. To support this dataset, modifications and updates to the NEAR/MSI ingestion application, msi2isis, and the camera model were needed. These modifications are included in the PR and submitted along with this issue.

The msi2isis application expands the original size of the PDS archive Eros images from 537x244 samples and lines to 537x412. The new remediation process was performed on expanded images and they will be archived in expanded form. msi2isis was modified to accept the expanded size to accommodate these images. This is automatically determined in msi2isis and image expansion of the lines is not performed on these images.

Additionally, the remediation was sufficient to retain the image edge that has been trimmed in the original images. A TRIM option was added to the msi2isis that make trimming optional. For the new data, we recommend TRIM=false so as to retain 33 pixels around all edges of the image. The default is to trim the edge which preserves pre-existing behavior.

The MisCamera model was modified to use the SpacecraftClockStartCount SCLK time rather than StartTime UTC to determine the observation time for MSI images. The SCLKs are typically more accurate than StartTime as UTC time is derived from the SCLK and may differ slightly with changes to subsequence SCLK kernels. This modification is manifested in msi2isis during label translation, and is now required for MsiCamera model. This changes makes the Eros dataset compatible with the sumspice application. sumspice applies SUMFILES produced by Gaskell's processing of image data for derivation of the Eros shape model.

In addition, a new version of the ISIS specific IAK has been updated to include light time correction and observer/target order for more accurate configuration of the geometric properties of ISIS camera models.

And finally, both the msi2isis application and MsiCamera unit tests have been replaced with CTests/GTests. The msi2isisapplication has been converted to a callable function to facilitate this work.
