USDA parser

newline between Property metadata begin('(')

OpenUSD currently does not allow a newline character before the opening parenthesis ( of property metadata. However, the tinyusdz parser currently accepts this syntax.

We believe the USD ASCII parser should support this newline to maintain consistency with Prim metadata, which already allows a newline before the metadata block begins.

here is the failure case in OpenUSD, but the success in TinyUSDZ

        rel material:binding = None
        (

        )
