* Fix Julia template for binary format
* Update julia samples
* fix missing check for the isBinary flag
Fix missing check for the isBinary flag in some places of the templates for julialang. The code would now be generated as Vector{UInt8} uniformly for binary strings. Binary strings that are also marked as files get generated as `String` data type on the client. That is because the Julia client expects a file name to be passed there.
