Binary streaming lite
This unit provides lightened version of BinaryStreaming library (which can
be found here: github.com/TheLazyTomcat/Lib.BinaryStreaming).
Over time, BinaryStreaming (further referred to only as BS) became bloated
with features that were only seldomly needed. This library was created for
situations, where core functionality was sufficient and/or using full BS
was undesirable (eg. because of long(er) compile times).
It provides functions for streaming of almost all basic types to memory
(Ptr_* functions) and to TStream descendants (Stream_* functions), with
exception being variants and small/tiny strings - they are not supported.
In provided functions, selection of endianness was removed - everything is
done in little endian.
And lastly, streamer objects were also completely removed.
For further details (eg. about how the primitives are streamed), please
refer to descriptions in the original BS.
NOTE - this entire unit was build from the original BS using a
specialized program, it was not manually written. The code was
copied, so if BS contains some error, it might appear here too.
Build from BinaryStreaming of version 2.2 (2025-03-08)
Version 1.1 (2025-03-08)

BinaryStreamingLite_UseAuxExceptions
If you want library-specific exceptions to be based on more advanced classes
provided by AuxExceptions library instead of basic Exception class, and don't
want to or cannot change code in this unit, you can define global symbol
BinaryStreamingLite_UseAuxExceptions to achieve this.

{
Following functions are returning number of bytes that are required to store
a given object. They are here mainly to ease allocation when streaming into
memory.
Basic types have static size (for completeness sake they are nevertheless
included), but strings and variants are a little trickier and must be scanned
to obtain the true size.
