add read_buffer_context and write_read_buffer_context

[braingram]

closes #873

Changes

Add read_buffer_context and write_read_buffer_context to weldx.asdf.util.

Update previous uses of read_buffer and write_read_buffer that inspect the result to use the context.

read_buffer and write_read_buffer were updated to use the new context to avoid code duplication. These were not removed to preserve the API and to leave them available for uses where the result is not inspected. Such as this test: https://github.com/BAMWelDX/weldx/blob/c2ee9b1f7cb8df8b2f4723884341e9e20dcd0d50/weldx/tests/asdf_tests/test_asdf_base_types.py#L15-L20
