update parquet and zarr media types, add others

[philvarner]

Related Issue(s):

• zarr media type should be application/vnd.zarr instead of application/vnd+zarr #1546

Description:

• Added new media types VND_APACHE_PARQUET and VND_ZARR with the current standard type for these format. The existing PARQUET and ZARR were retained, with a text warning about being deprecated. There's no good way in 3.10 to even document that these are now deprecated, and I both couldn't get the pattern of making it a property and adding the @deprecated annotation to work, and we'd have to add a dependency on the deprecated package.
• Add new types: COPC and VND_PMTILES (defined in the STAC Best Practices doc). Did not add OGC 3D Tiles as there is still some uncertainty about what the media type for that should be, and it's not a common one.
• updated multidict from yanked "6.3.2" to 6.3.3
