Support Node >=v14

[stewart-lore]

Most apps that will use seaport-js will be webapp clients. It doesn't make sense to enforce the latest node version when node is not used on the client.

I'm requesting that you downgrade the seaport-js node requirement to 14, ie >=v14.19.1 or just remove this restriction altogether.

The reason I'm asking is because I'm up-taking seaport on my client app which is served by a Node 14 server-- it's turning out to be a challenging upgrade. Since the seaport protocol was just released, it is time sensitive for my app to upgrade before you disable wyvern.

Thanks.

We're also in the process of integrating seaport for https://github.com/blockchain/blockchain-wallet-v4-frontend and would also prefer >= node 14, or at the least unpin the patch version.
