Android 11 OTAs use the same `payload.bin` format, but lack the `metadata.pb` protobuf representation of the OTA metadata. This commit adds support for parsing the legacy plain-text `metadata` format. Like before, the output files will still contain both the legacy and protobuf representations. Note that the legacy format allowed OEMs to specify arbitrary key/value pairs. These will be discarded during patching because they cannot be represented in the protobuf format, which is used in avbroot's internal representation.
