readme: Enforce 100 column width

The readme has gotten a bit messy with various contributors using
different collum width. Make it all 100 so that new contributors have
some chance of keeping it tidy.

On top of that, use "natural" line breaks if it assists reading/editing
i.e., don't be dogmatic about column length.

## Known limitations
### Consensus
This library **must not** be used for consensus code (i.e. fully validating
blockchain data). It technically supports doing this, but doing so is very
ill-advised because there are many deviations, known and unknown, between
this library and the Bitcoin Core reference implementation. In a consensus
based cryptocurrency such as Bitcoin it is critical that all parties are
using the same rules to validate data, and this library is simply unable
to implement the same rules as Core.

Given the complexity of both C++ and Rust, it is unlikely that this will
ever be fixed, and there are no plans to do so. Of course, patches to
fix specific consensus incompatibilities are welcome.

### Support for 16-bit pointer sizes
16-bit pointer sizes are not supported and we can't promise they will be.
If you care about them please let us know, so we can know how large the interest
is and possibly decide to support them.

## Documentation
Currently can be found on [docs.rs/bitcoin](https://docs.rs/bitcoin/).
Patches to add usage examples and to expand on existing docs would be extremely
appreciated.

## Installing Rust
Rust can be installed using your package manager of choice or
[rustup.rs](https://rustup.rs). The former way is considered more secure since
it typically doesn't involve trust in the CA system. But you should be aware
that the version of Rust shipped by your distribution might be out of date.
Generally this isn't a problem for `rust-bitcoin` since we support much older
versions than the current stable one (see MSRV section).

## Pull Requests
Every PR needs at least two reviews to get merged. During the review phase
maintainers and contributors are likely to leave comments and request changes.
Please try to address them, otherwise your PR might get closed without merging
after a longer time of inactivity. If your PR isn't ready for review yet please
mark it by prefixing the title with `WIP: `.

### CI Pipeline
The CI pipeline requires approval before being run on each MR.
In order to speed up the review process the CI pipeline can be run locally using
[act](https://github.com/nektos/act). The `fuzz` and `Cross` jobs will be
skipped when using `act` due to caching being unsupported at this time. We do
not *actively* support `act` but will merge PRs fixing `act` issues.

## Policy on Altcoins/Altchains
Patches which add support for non-Bitcoin cryptocurrencies by adding constants
to existing enums (e.g. to set the network message magic-byte sequence) are
welcome. Anything more involved will be considered on a case-by-case basis,
as the altcoin landscape includes projects which [frequently appear and
disappear, and are poorly designed anyway](https://download.wpsoftware.net/bitcoin/alts.pdf)
and keeping the codebase maintainable is a large priority.

In general, things that improve cross-chain compatibility (e.g. support for
cross-chain atomic swaps) are more likely to be accepted than things which
support only a single blockchain.
