Create an empty output byte stream having an initial buffer capacity of at least the specified initialCapacity (in bytes) and that will use the specified (compile-time-defined) versionSelector as needed (see {Versioning}). Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used. Note that the versionSelector is expected to be formatted as "YYYYMMDD", a date representation.
