Add support for Base network (#31)

New deployment on Base with the following parameters:

```sh
export RECEIVER='0xA03be496e67Ec29bC62F01a428683D7F9c204930' # solver reward used in Base (changes depending on the network)
export TO_TOKEN='0x4200000000000000000000000000000000000006' # WETH in Base
export KEEPER='0x05C5494572E4aB2d48D3AB3aAF6bD4e7b1c98382' # same as in mainnet and Gnosis
export SETTLEMENT='0x9008D19f58AAbD9eD0D60971565AA8510560ab41' # same as in every network we support
export APP_DATA='0xbcca8463f460f14bca0185afeeb75923ee4434612f41063d0171b1e743ffe84b' # same as in mainnet and Gnosis
export TARGET_SAFE='0x423cEc87f19F0778f549846e0801ee267a917935' # address that uses the module
export MIN_OUT='100000000000000000' # 0.1 ETH, same as in Arbitrum
```

~Note that I removed the deployment on Gnosis because it's outdated: the
new one is at
[0x18b990DB05Bd4369A1b7259EfE5fC2a362508d7B](https://gnosisscan.io/address/0x18b990DB05Bd4369A1b7259EfE5fC2a362508d7B#readContract)
but there's no corresponding broadcast file available.~ (Addressed in
d2185ff.)

I also regenerated `networks.json` with the script at
`dev/generate-networks-file.sh`.

### How to test

Check the parameters and check verified code on Etherscan.
