Fintan Halpenny 2584ecdb0a radicle: Pin timestamp for testing
When testing the CLI, "since"-calculations will result in different
values over time:

    now
    1 month ago
    2 months ago
    10 months ago
    1 year ago
    10 years ago

Initially, the solution was to use the wildcard match from `snapbox`,
`[..]`, to match on these values. However, since these values change
in length it means that they will affect the width of the tables
produced by the CLI.

To ensure the width is stable across runs over time it's possible to
use a time that is the same as the commit time used at testing.

To do this the `Timestamp` type is now a newtype which has a
constructor `now` which will use the `RAD_COMMIT_TIME` env variable
for construction, if it's available and in debug mode. This ensure
that all "since"-calculations will result in `now`.

When contributing to another's project, it is common for the contribution to be
of many commits and involve a discussion with the project's maintainer. This is supported
via Radicle's patches.
Here we give a brief overview for using patches in our hypothetical car
scenario. It turns out instructions containing the power requirements were
missing from the project.
```
$ git checkout -b flux-capacitor-power
$ touch REQUIREMENTS
```
Here the instructions are added to the project's README for 1.21 gigawatts and
commit the changes to git.
```
$ git add REQUIREMENTS
$ git commit -v -m "Define power requirements"
[flux-capacitor-power 3e674d1] Define power requirements
1 file changed, 0 insertions(+), 0 deletions(-)
create mode 100644 REQUIREMENTS
```
Once the code is ready, we open (or create) a patch with our changes for the project.
``` (stderr)
$ git push rad -o patch.message="Define power requirements" -o patch.message="See details." HEAD:refs/patches
✓ Patch a8926643a8f6a65bc386b0131621994000485d4d opened

It will now be listed as one of the project's open patches.
