Fix handling of multi-series series_annotations

[nick4f42]

Currently, values for series_annotations can be:

• Vector of text e.g. ["foo", "bar"]
• (x, args...) where x is a vector of text and args are the font/marker options
• 1-row matrix of vectors of text e.g. permutedims([["foo"], ["bar"]])

Changes were made for specifying annotations for multiple series:

• Matrix of text (one column for each series)
• 1-row matrix where each element is x or (x, args...) where x is a vector of text and args are the font/marker options
• A tuple (x, args...) where x is one of the previous two
  • The args in the inner tuples override the args in the outer tuple

Fixes #4073

That looks great, thank you. Can we add one more test for the matrix case?

There was already one for the matrix case but I just changed it to use [a c; b d] instead of [[a, b] [c, d]] so it's more clear that it's a matrix of scalars and not a row matrix of vectors. I also added another test case for the tuple(text_matrix, ...) case.

Let me know if there's anything else that should be changed!

Great, thank you!
