Make TLink parameter in LinksOptions configurable and reorder template parameters

This change addresses issue #116 by:
- Reordering template parameters to put TLink as the second parameter
- Removing the default value from TLinkAddress as requested in issue comments
- Updating LinksOptions template signature to match the desired format from the issue
- Updating test files to use the new parameter order

The new parameter order is:
template<TLinkAddress, TLink, TWriteHandler, TReadHandler, VConstants>

This makes LinksOptions more adjustable by users and reduces code duplication.
