Allow the client to request arbitrary numbers of captchas

[forgetso]

Client applications should be able to call the provider API and request an arbitrary amount of captchas. As long as the amount is greater than the configured minimum and less than the configured maximum (to avoid load issues), these should be returned by the provider API.

By allowing the dapp user to solve many captchas at once, they are able to submit the solutions to all of the captchas in a single transaction, instead of submitting multiple transactions.

Question - will this aid bots and is it perhaps a poor design decision?
