Performing a CC Tap on DevNet or LocalNet

When writing scripts and setup it is important to have funds present, this can be very tedious on blockchains. Therefor most blockchains support some form of a faucet (that allows to receive a small amount of funds to play with). On canton we allow the tap method that is only present on DevNet (or LocalNet), by using this you can stock funds to easily attempt some of the CC transfer flows: 
import { SDK, localNetStaticConfig } from '@canton-network/wallet-sdk'

export default async function () {
    const sdk = await SDK.create({
        auth: global.TOKEN_PROVIDER_CONFIG_DEFAULT,
        ledgerClientUrl: localNetStaticConfig.LOCALNET_APP_USER_LEDGER_URL,
        amulet: global.AMULET_NAMESPACE_CONFIG,
    })

    const myParty = global.EXISTING_PARTY_1

    await sdk.amulet.tap(myParty, '2000')
}
This is an important pre-requisite for the creating of transfer in your script.
