Tobin C. Harding cb9893c4a9 Add Target and Difficulty types
Currently we use the `Uint256` type to represent two proof of work
integers, namely target and difficulty (work).

It would be nice to not have a public integer type that is not fully
implemented (i.e., does not implement arithmetic etc as do integer types
in stdlib). Instead of implementing all the stdlib functions we can
instead add two new wrapper types, since these are not general purpose
integers they do not need to implement anything we do not need to use.

- Add a `pow` module.
- Put a modified version of `Uint256` to `pow`.
- Add two new wrapper types `Target` and `Difficulty`.
- Only implement methods that we use on each type.

Note this patch does not remove the original `Uint256`, that will be
done as a separate patch.

Tobin C. Harding 022730bd8d Add a workspace to the top level directory.
Create a directory `bitcoin` and move into it the following as is with
no code changes:

- src
- Cargo.toml
- contrib
- test_data
- examples

Then do:

- Add a workspace to the repository root directory.
- Add the newly created `bitcoin` crate to the workspace.
- Exclude `fuzz` and `embedded` crates from the workspace.
- Add a contrib/test.sh script that runs contrib/test.sh in each
  sub-crate
- Fix the bitcoin/contrib/test.sh script

Martin Habovstiak 0e1b99359c Added fuzz test for `Script::bytes_to_asm_fmt`
This adds fuzz target for `Script::bytes_to_asm_fmt` which could
panic due to overflow in the past. Fuzzing should decrease the risk of
other panics.

Martin Habovstiak a291fee23c Removed fuzztarget feature
It seems to be unused and when there's a need for it it's better to use
`--cfg fuzzing` as in `rust-secp256k1 ` and `bitcoin_hashes`.
