Readme notes about limitations are confusing.

README > Limitations / Pitfalls

This is how I read it first time until I decided this makes no sense:

Immer only supports plain objects and arrays.

My thoughts: So no support for strings and integers?
Assumed meaning: It does not support Map and Set (clear in the 1.5.0 README).

For arrays it is assumed only numeric properties (and length) are used.

My thoughts: So arrays cannot contain strings?
Assumed meaning: No idea.

In the same section the

4. Class instances are not, and will not be supported. Read here more on why that would be a [confusing, conceptual mismatch]

confuses me. It looks like here should be a link and [confusing, conceptual mismatch] looks like it is a draft where the author still wanted to decide, what to actually write.

Clarified the readme on both points, feel free PR further changes if anything is still unclear
