Several LEDES Formatting Improvements

Submitting Bills in a LEDES format is very important for many law firms. We've made several improvements to the formatting of those files when generating them in Curo365.

In the situations where Split Billing was being utilized, the LEDES file also was split unnecessarily. Now when you generate a LEDES file for a Split Billing scenario, only a single LEDES file is generated.
