Add adaptive mask plot to report

[tsalo]

Closes #1072.

Changes proposed in this pull request:

• Create a new function named tedana.reporting.static_figures.plot_adaptive_mask, which creates a figure showing the base mask, the denoising mask (adaptive mask >= 1), and the classification mask (adaptive mask >= 3) overlaid on top of the mean optimally combined image.
• Add the adaptive mask figure to the HTML report.

I think that's better. I noticed the figure has some blank area above and below the actual figure itself. This means that effectively, the brains are not going to be 500px in height, but the whole thing with the blank area above and below will be. I don't know where this blank area came from. It must be from the function that generates the image.

See below 👇 The blue area shows the whole <img> component, containing the brains plus the blank areas I mentioned.

I dropped the brainplot class and things look better. @eurunuela WDYT?

[tsalo]

I'm working on improving the figure- the 3-echo one was looking weird.

[tsalo]

Okay it's looking a lot better now.
