Retry Fix printing of multiline values, and allow colors in showed values

[MasonProtter]

This is a continuation of #341 after it was reverted because it errored when encountering an AnnotatedString.

Seems to be working with AnnotatedString.

julia> let n = 20
           xs = Float64[]
           p = Progress(n)
           for iter = 1:n
               append!(xs, rand())
               sleep(0.5)
               plt = lineplot(xs)
               str = Base.AnnotatedString(" julia", [(2:6, :face, rand((:magenta, :red, :blue, :green)))])
               ProgressMeter.next!(p; showvalues = [(:UnicodePlot, plt), ("An annoted string", str2)])
           end
       end

The downside is that styled strings will get a " wrapped around them as you can see in the video, so if anyone has any better suggestions for how to deal with this generically, I'd be open to input. cc @MilesCranmer

Probably worth adding some tests; also see the code coverage

[MilesCranmer]

Does this "empirically it is needed" change at all with this modified calculation? Is there a test for this that verifies it is/is not needed?

[MasonProtter]

That's an old comment from before my PR. I did try some tests to change that value, and it causes the number of printed lines to shrink or expand each iteration if you change it.

[MilesCranmer]

Yeah I assumed it was old, I was just wondering if it was no longer relevant since it’s now a different method for counting lines

[MilesCranmer]

Is this repr the cause of the explicit quotes showing up?

[MasonProtter]

Yes. Trying to show it like in the previous commit causes it to show up as AnnotatedString(" julia", ...)

[MarcMush]

maybe with sprint? https://docs.julialang.org/en/v1/stdlib/StyledStrings/#Applying-faces-to-a-AnnotatedString

[MasonProtter]

Yeah I'll throw some tests together soon, I just wanted to put the PR up for now to see if people have suggestions for how to deal with these annotated strings
