Investigate moving to JSDOC only insterad of TS

[Tokimon]

Since every function is documented by JSDOC anyway, maybe consider only using that over TS for type validation.

Issues to sort out

• Have types understood by the IDE
• Generate documentation JSON as normal
• How to handle complex types

Advantages

• No extra build step to transform TS to JS
• Less Type complexity to handle
• Possibly easier to handle complex types
• Keep files as they are written if a "download-to-project" approach is taken (instead of a recompiled JS file from TS)

Disadvantages

• No typescript means less confidence in the project (?)
• Possibly less ways to handle complex types
