Investigate options for saving tables with standard asdf table tag

[braingram]

asdf-astropy currently does not implement an asdf core table writer:

asdf-astropy/asdf_astropy/converters/table/table.py

Lines 47 to 58 in b532105

	class AsdfTableConverter(Converter):
	tags = ("tag:stsci.edu:asdf/core/table-*",)
	types = ()
	def to_yaml_tree(self, obj, tag, ctx):
	msg = "astropy does not support writing astropy.table.Table with the ASDF table-1.0.0 tag"
	raise NotImplementedError(msg)
	def from_yaml_tree(self, node, tag, ctx):
	from astropy.table import Table
	return Table(node["columns"], meta=node.get("meta"))

Investigate options for triggering asdf-astropy to write a restricted table that is compliant with the core table schema to aid in producing files that might be more easily supported by non-python implementations of asdf.
