Support multiple standards (e.g. ATAG or Canada.ca Style Guide checklists)

Feature request - not sure how to implement this. Currently the implementation is highly dependent on hierarchical numbering like in EN 301 549.

[juleskuehn]

This can be implemented by adding an additional "clause set" object which is parent to clauses. A new clause set can be created for each standard. Contract language can be considered a standard. Each standard needs to be implemented using hierarchical numbering where only leaf nodes contain testable requirements. Any code relating to a "clause tree" will need to be updated to operate on a list of clause set objects rather than clauses directly. The clause tree function will output a separate clause tree for each clause set.

This may cause issues in the following areas:

• Not every standard should have the same structure (e.g. most do not have a "determination of conformance" written into the standard)
• The output pug templates would need to be modified to include the different standards, taking into account the structure of each.
