the following fields in the message `content`:
* 4.1.4.A. `type` equals the string `group/exclude`
* 4.1.4.B. `excludes` is an array of objects with the shape
`{id, groupFeedId, sequence}` where `id` is the root metafeed ID of `c`,
`groupFeedId` is `Gc`'s ID, and `sequence` is the sequence number of the last
message `a` possesses from `Gc`. In this case `c` is the only excluded
member, so we only have one `{id, groupFeedId, sequence}` object but Section
`{id, groupFeedId}` where `id` is the root metafeed ID of `c` and
`groupFeedId` is `Gc`'s ID. In this case `c` is the only excluded
member, so we only have one `{id, groupFeedId}` object but Section
4.1. also supports excluding multiple members at once.
* 4.1.4.C. `recps` is an array containing a single string: the group ID for
`G`, signalling that this message should be box2-encrypted for the group `G`

* 4.8.2.A.A. `R` is the set of all remaining members after the removal of `c`. `MR` is the set of all of `R`s messages in this group. `Sc(m)` is, given a message `m`, found by looking at the `previous` array in `m`'s `group` tangle, seeing if there's a message from `Xc` referred to in it, and in that case getting the sequence number of that message. `SXc` is the maximum `Sc(m)` for all messages `m` in `MR`.
* 4.8.2.B. (Fetching remaining members) `a` SHOULD continue to fetch messages
from group feeds `Xb` belonging to every remaining member `b` in `X`. See figure
9 as an example.
