load maki icon

[birkskyum]

@archmoj, links to icons/sprites are usually inside the style.json itself, but for compatibility if a maki icon (gh repo) is detected as missing, this PR will make sure it's downloaded and rendered.

Thanks very much for the PR.
Please download & update new baselines from https://app.circleci.com/pipelines/github/plotly/plotly.js/10929/workflows/4bdb5573-f32a-4762-97d1-054c349c9dfd/jobs/240837/artifacts

When comparing the diffs here https://github.com/plotly/plotly.js/pull/7015/files#diff-f0fbe3130eb2e4f0e1c8faf5ba166a839a3dfdce358c2e60d6f9c8ee5ccf475b
I see a lighter color being used on the mapbox baselines.
But the symbols here show in black!
Does marker.color work?

[birkskyum]

@archmoj setting marker.color: '#ffff00', (yellow) appear to change the color of the line between the icons for both mapbox/maplibre.

[birkskyum]

This is an area where both mapbox/maplibre are too strict. We're planning to add proper SVG support, which would make things easier to style and improve in other areas too - maplibre/maplibre#175.

Please add 'map_angles' to isOtherFlaky list in test/image/compare_pixels_test.js.
Thank you!

Thanks very much.
FYI I'll fix the b64 image test on my PR.
