Sanitize Redfish string fields to strip non-ASCII/non-printable characters

Browse Source 
IOM1's HostName field contains binary artifacts that decode to garbage
unicode characters (e.g. 𳇀 prefixing a UUID). Strip any character
outside printable ASCII (0x20–0x7F) from all string fields returned by
_parse_network_data.
