Provide Export Functions of Load Shapes Library

It would be useful to add two separate functions to the load shape library for current/future users, particularly if the functionality of the load shape process allows for load shapes to be used between measure package (as is planned).

First, it would be good to be able to export the library table itself as a csv or excel file. We have thousands of load shapes now, and searching/filtering in the current table can be challenging. Being able to export to excel and review there would be helpful.

Second, being able to export the actual hourly data for a specific load shape in the library. This would be important for users who want to adopt load shapes between measure packages, or use them for other purposes, such as billing impact or other hourly analysis.
