Retain Language Identifiers for VersionInfo Resources

[Washi1337]

Problem Description

Win32 resources are organized by language ID at the deepest level of the internal folder structure in the data directory. Currently, VersionInfoResource::WriteToDirectory does not retain this language ID.

Proposal

Add an overload for VersionInfoResource::FromDirectory that obtains a language-specific version of the requested resource, such that their corresponding WriteToDirectory method can reuse this language ID when constructing and inserting new data entries.

Alternatives

The user could manually adjust the language IDs after calling WriteToDirectory. This is not intuitive however, as it requires looking up the newly generated and inserted resource data entries in the folder structure.
