-- BREAKING CHANG --
Using multiple paths for a sources in the config file caused many
problems as the syntax was unclear and problems existed in edge cases.
This PR changes the definition of sources in config profile files:
- a single path path can be specified as before, i.e. using `source =
"/my/path"`.
- multiple paths must now be given in an array:
```
source = ["/my/path1", "/my/path2"]
```
Note that
```
source = "/my/path1 /my/path2"
```
is now interpreted a a single path using the dir-tree "my","path1 "
(with space), "my", "path2".

Adds the `--check-index` option. This is an alternative to `rustic
repair index` in cases where the repository is read-only and cannot be
repaired.
Using this option, the index is checked against existing pack files and
missing information is read from the pack headers.
The intention of this PR is to make it easier (more straight forward) to
write `rustic` integration tests by utilizing the `assert_cmd` and
`predicates` crates.
