Define npm package structure

The package will have the following structure:

artifacts/               # copy of deployments/<network>/
build/contracts/         # build artifacts
contracts/               # source code
deploy/                  # deployment scripts
export.json              # single-file deployment export

`artifacts/` - is a directory containing deployed contracts artifacts
for the network the package is being created. It is assumed that a
package is published for each supported network separately,
so we don't need to create seperate directories per network.

`build/contracts/` - is a directory containing compiled contracts
artifacts in the Hardhat format.

`contracts/` - is a directory containing contracts source code.

`deploy/` - deployment cripts (can be used in other projects using
hardhat for local development)

`export.json` - lightweight deployment data in a single file.
