look vector needs clear definition in the document #334

Jira: https://asfdaac.atlassian.net/browse/TOOL-2081

Describe the bug Emily Fedders in GI reports that she is confused about the definition of look vector in the insar_product_guide. We have clear definition of look vector in the _lv_theta.tif.xml and _lv_phi.tif.xml in the product. For example, in the _lv_phi.tif.xml file, the look vector is described as "The look vector orientation angle is define d as the angle between the East direction and the projection of the look vector (pointing back towards the sensor) on the horizontal surface plane. The pixel values indicate the SAR look vector orientation angle at each map pixel, with values of 0 indicating east, and ranging from to pi/2 (north) to -pi/2 (south), expressed in radians."

Expected behavior We hope to include the clear definition of look vector in the insar_product_guide.
