Allow language identifiers to be customized and preserved in IconResource

[Washi1337]

Problem Description

Currently, IconResource::WriteToDirectory always constructs resource directories with the language identifier 1033.

Proposal

Add Lcid properties to the classes related to icon resources, similar to how is done in VersionInfoResource (see #457).

Alternatives

None

Additional Context

No response

I'm attempting to replace rcedit in Velopack so I can set PE resources while running on Linux, I think this should be classified as a bug rather than an enhancement. This and #532 are the current blockers.

[Washi1337]

Initial rework of IconResource can be found in PR #565, which should support LCID customization.

@caesay Sorry for the very late reply, I must have missed the notification for this. It depends on whether you simply need to copy over resources from one PE to another or actually have rich editing where you need full interpretation and reconstruction of the resource data. Copying over is already fully supported (by simply copying the directories in PEImage::Resources). This issue only refers to the latter scenario.

No worries, I am doing rich editing (eg. setting a new icon, re-creating custom version tables) and I managed to find a workaround in the meantime. Thanks for your work on this awesome library!
