Implement `WrapError` for `Option<T>`. This is inline with `anyhow` that
also implements `Context` for `Option<T>`.
The implementation requires us to introduce a `DisplayError` internal
only type, that creates an error from a type that only implements
`Display` (`Report::from_adhoc` requires the type to also implement
`Debug`, but `WrapError` only requires it to implement `Display`).
For this I copied `MessageError` and adapted it to implement `Debug`
using the underlying type's `Display` impl. This is a bit of a hack, but
anyhow does [something similar][1].

* Fix `clippy::doc_lazy_continuation` lints
* Fix `dead_code` warnings in tests.
Protect code used in some tests based on features with feature
checks.
* Fix `clippy::needless_borrows_for_generic_args` lints
* Remove a useless conversion
* Remove a cfg_attr check for `track_caller`
This shouldn't be needed here as the test is already ignored.

Diagnostic impls are no longer reset to default when converting a
`Report` into a `Box<dyn Diagnostic>`. Also prevented `Report` vtables
and handlers from being kept around on the heap after conversion.
This can be used to avoid awkward `start..(end + 1)` constructions,
which will trigger the `clippy::range_plus_one` lint.
I added a single impl for `InclusiveRange` rather than a blanket
`impl<T: RangeBounds> From<T> for SourceSpan` for two reasons. The first
is that the blanket impl would be a breaking change (because dependent
crates may currently define a type `T: RangeBounds` and also have `impl
From<T> for SourceSpan`). The second is that this would allow one-sided
ranges (`..x`, `x..`). In order to support bounded-below ranges, we
would need to change `SourceSpan` so that `length` may depend on the the
specific `SourceCode` instance. That seems like an unlikely use case.
This improves `get_lines()` logic by using a string-buffer with a capacity hint.
That avoids growing the buffer from zero each time, saving a bunch of reallocations.
* fix(docs): `alt` attribut for `single-line-example.png`
The white line breaks in the `alt` attribute prevented the `single-line-example.png` image from being displayed.
* Revert "fix(docs): `alt` attribut for `single-line-example.png`"
This reverts commit 2e97d568aa.
* fix: image link in `lib.rs` instead of `readme.md`
* feat(docs): cargo make readme

When a snippet couldn't be read (typically because the span didn't fit
within the source code), it and the rest of the diagnostic were silently
dropped, which was confusing to the developer.
Now, in place of the snippet, print an error message with the name of
the failed label and the error it triggered, then proceed with the rest
of the diagnostic (footer, related, ...)
