[Feature Request] Add a field for heights and pagenotes that can be used for the id of the obsidian block reference. #68
Description
The id contains the character "_", which is not a legal character for Obsidian block references. This prevents the automatic assignment of block references directly to hypothesis data after synchronization.
Maybe add a field such as mapped_id, which is mapped from the hypothesis id and whose characters are all within the legal range of obsdian block references.
