Should Map be Filterable?

The Filterable used in ⬇️ doesn't seem to support Map?

https://github.com/ramda/ramda/blob/980b3bf7712adb8ad8b5d9b2c6aca525cb3cf143/source/filter.js#L11-L16

As best I can tell it fails the _isobject check: https://github.com/ramda/ramda/blob/980b3bf7712adb8ad8b5d9b2c6aca525cb3cf143/source/filter.js#L38-L40

Because: Object.prototype.toString.call(new Map()) === '[object Map]' !== [object Object]

Then fall through to this which fails because Map doesn't have .length: https://github.com/ramda/ramda/blob/852e252041fbbd8e341d0d3dc7749c2b5bd692a7/source/internal/_filter.js#L1-L6

I'm not too sure of ramda internals, but could it use the iterable protocol instead of assuming listwith .length?
