Is it possible to stream inputs into rustac.write?

[hrodmn]

I have a use-case where I want to write ~100-300k STAC records to a stac-geoparquet file. I have found that this process is very memory intensive, though, so I am wondering if there is some way to reduce the memory footprint of my write operation by avoiding loading the entire list of items into memory before handing them off to rustac.write.

Converting this to an issue, as it'd be a nice feature to have: #174
