Helper function to parseADA to Lovelace

[nstanford5]

Most DApps will present users with the ability to input token amounts to a UI component. Users typically think in terms of ADA amounts, but we need to send Lovelace amounts to the blockchain.

Should the SDK include a simple helper function to parseADA to Lovelace?

Something like..

const parseADA = (num: number) => { return num * 1000000; };

On the other side of that, when querying the blockchain for amounts -- it will return Lovelace that needs to be formatted to ADA to present to users.

Should we also include a formatLovelace function?

I would like to have this type of functionality in a broader concept called TemplateParameters. Currently, that is part of Marlowe Extended, you can check it on the Playground's metadata tab

I think it would be good to separate the concept from Marlowe Extended and make a sort DSL with constraints, to be able to say stuff like amount > 24, amount1 <= amount2, timeout1 in_between [timeout2 timeout3], etc.
