* Passing the Default BIG Arg to Serialize Functions * Fails on Ac Files * Compiles w/ little endian autocode * Unit Tests Pass * Little Endian deserializeTo & Unit Test Little Endian SerDes * Add little-endian SerDes examples to docs * Add & Respect Endianness for Array Lengths & Remove unneeded Fw:: Prefix * Switch to enum class Endianness * Fixes for enum class Endianness * Run code formatter * Bump fpp to v3.1.0a4 * Update Fw/Time/Time.hpp * Update Fw/Time/Time.hpp --------- Co-authored-by: Rob Bocchino <bocchino@jpl.nasa.gov> Co-authored-by: M Starch <LeStarch@googlemail.com>
