* Since these types are more prevalent than originally designed, it
makes more sense to remove the namespace for ease of typing/naming.
* Also add a specialised type 'bytebuf' for an array of bytes.
* This makes mapping easier to SWIG since there's no special casing for
namespaced arrays. Especially so for nested cases like
rdctype::array<rdctype::str> -> rdcarray<rdcstr>
* For the most part the interface is stl-compatible, but we have a few
little changes of our own for convenience.
* This class is still needed after deleting the C# UI, because we don't
want to pass C++ stl structs over module boundaries and possibly run
into hard to diagnose incompatibilities.
To quote the Qt documentation for QFileDialog::setNameFilters:

Admittedly, one of these usages is Windows-only and we are using the
native file dialog there, but we might as well be consistent.
In most of these cases, the open file dialog won't even display a file
without the proper extension, so this helps ensure the user doesn't
accidentally misplace their files. The one exception is *.rdc, which
could be found without the extension, but could not be opened.
* If there's a variable which is unused and has no binding declared, it
will be sorted to the end of the list and given a binding of 0. We
don't want to let this override a valid binding for 0, so make sure we
prioritise any variable which is marked as used over one that is
unused.
* For D3D this is overkill as we just stuff the uint32_t flags into a
string. However for SPIR-V this will let us store the parameters from
an OpModuleProcessed.
* This means that each time you open the dialog you don't start with an
empty set, instead you start with the set of counters you had
previously selected.
