Progress of `Remote: checking segment file /whatever/data/17/17078...`

## Have you checked borgbackup docs, FAQ, and open GitHub issues?

Did not found anything; but I did not check in borg 2.0.

## Is this a BUG / ISSUE report or a QUESTION?

Feature request. And really just a minor comfort feature.

## System information. For client/server mode post info for both machines.

#### Your borg version (borg -V).

IIRC remote is borg 1.2.4 (Hetzner StorageBox).

#### Full borg commandline that lead to the problem (leave away excludes and passwords)

`borg check --repair --debug`

## Describe the problem you're observing.

`borg check --repair --debug` prints:
```
[...]
Remote: checking segment file /whatever/data/17/17078...
[...]
```
and
```
[...]
Remote: compacting segment 4319 with usage count 3 (maybe freeable: 98.88% [100498350 bytes])
[...]
```

I therefore know which segment borg is checking or compacting right now, but I do not know how many are still to go. (i.e. should I grab a coffee or should I go to bed? 😀).

borg already prints this once at the beginning, but it is very likely that the terminal scroll buffer is too small to being able to scroll all the way up 😅:
```
Remote: Segment transaction is 18594
Remote: Determined transaction is 18594
Remote: Found 4314 segments
```

While analyzing archives, there is such a count:
```
[...]
Analyzing archive a5a5b138021d-2023-10-31T23:01:07.973430 (2/61)
[...] ^^^^
```

This is really just a minor feature request. It might still be nice to know about the progress, so one can estimate whether the operation is taking some more minutes or some more hours :)

Related: `borg info` (maybe only `--json`) could also print something like `segments_count` and `max_segment_index` -- but that is probably only useful for some very special use cases.
