Fix: change maxBodyLength axios config to allow large inputs

Closes #479

Thanks @nials-relevant for your contribution. I'm a bit torn on accepting this change mostly because inputs and outputs to DF APIs are supposed to be relatively small, and therefore the default limit placed by axios makes for a convenient way of indirectly enforcing this on a DF client.

However, I also recognize that users who know what they are doing would benefit from this. Perhaps there's a middle ground where this setting can be configured, but we log a warning whenever large inputs over a given size are detected. Would something like that fit your usecase, @nials-relevant ?
