Remove is_bjd_excluded_optimized_type(), which has no caller left; fix two comments

Browse Source 
is_valid_optimized_type() rejects the markers BJData excludes, so the reader
no longer needs its own list; the test now checks is_valid_optimized_type()
of a BJData reader against the writer's list. The BSON size comment now says
that open_bson_document() rejects a size below 5.
