naming things

[GregorDeCillia]

• [ ] Make sure all function arguments use a consistent naming scheme.
• [x] Always use uris when ids are used as function arguments.
• [ ] Namespace functions for specific endpoints by their endpoints (sc_table_saved-list())
• [ ] Decide whether certain logic should be only accessible as a R6-method rather than a regular function

[GregorDeCillia]

About point 4: It is probably a good idea to make the parsers available both as functions and methods and use a consistent naming scheme. The logic should be implemented in the functions and the methods call the functions.

## methods without arguments
sc_table_meta(obj)
obj$meta

## methods with arguments
sc_table_field(obj, i)
obj$field(i)

This way, the functions can be developed and documented independently.
