Hello, i was curious if there is anyway to use reinterpret on a UInt8 vector but flip the endianness of the interpretation?  
If it cant be done using the reinterpret function directly would anyone know how to flip the values after?

Julia has a variety of functions for this [I/O and Network · The Julia Language](https://docs.julialang.org/en/v1/base/io-network/#Base.ntoh). `ntoh`, `hton`, `ltoh`, and `htol` depending on what you want.
