Add plugin-specific metadata to a running packet. This will take some describing. You accumulate any number of bits of metadata into arbitrary fields, and then later on serialise these to json.
Arguments
- name
The name of the plugin; must be the same as used in orderly_plugin_register and orderly_plugin_context
- field
The name of a field to add the data to. This is required even if your plugin only produces one sort of data, in which case you can remove it later on within your serialisation function.
- data
Arbitrary data to be added to the currently running packet
