[Feature Request]: pass keyword arguments to zopen to accommodate non english platforms

[rkingsbury]

Problem

User needs to be able to pass kwargs through to zopen (e.g., in JSONStore) in order to accommodate non-english platforms.

See materialsvirtuallab/monty#641 (comment)

zopen fails on some language platforms due to lack of explicit encoding (UnicodeDecodeError) #641

Proposed Solution

• Identify anywhere in maggma that uses zopen
• Add passthrough kwargs from the Store.__init__ method to zopen so that users of other platforms can explicitly set character encoding

Alternatives

No response
