Add .setMaxZoom/.setMinZoom method

[peterqliu]

Analogous to #2175, except that it allows setting the zoom bounds after the map is already declared.

[peterqliu]

An alternate format could be map.setZoomBounds({min:0, max:20})

[lucaswoj]

This would be awesome!

It think our preferred API would be

map.setZoomBounds(0, 20)

[peterqliu]

@lucaswoj super naive stub here. Would appreciate some scope/context around this

[lucaswoj]

@peterqliu Looks like you're on the right track!

Next steps

• turn this stub into a pull request
• take minZoom and maxZoom as separate parameters rather than an array
• document the parameters in the docblock comment above the method.
• add a way to unset the zoom bounds too
• add some simple unit tests for this method

Let me know if I can help in any way.
