Fixed rolling shutter applyJitter (#4976)

### Fixed

- Added check to determine if poles were a valid projection point in ImagePolygon when generating footprint for a map projected image. [#4390](https://github.com/USGS-Astrogeology/ISIS3/issues/4390)

- Fixed the Mars Express HRSC SRC camera and serial number to use the StartTime instead of the StartClockCount  [#4803](https://github.com/USGS-Astrogeology/ISIS3/issues/4803)

- Fixed algorithm for applying rolling shutter jitter. Matches implementation in USGSCSM.

  /**

   * Iteratively finds a solution to "apply" jitter to an image coordinate.

   * Each iteration adds jitter to the original image coordinate until it finds

   * an image coordinate that maps back to to the original image coordinate when

   * jitter is removed. This is similar to how we handle applying radial distortion.

   *

   * Note: If the jitter varies significantly (>1 pixel difference) then it is possible

   * for there to be multiple solutions to the inverse problem and it is impossible to

   * know which one to choose.

   *

   * @param sample Image sample to apply jitter to.

   * @param line Image line to apply jitter to.
