Better inform user about deposit limits in the contract

[kelsos]

Description

Currently, if the user tries to deposit a bigger amount than the limit. The deposit transaction will fail and a really unhelpful will be displayed. In the newer contracts, the limits are set during the deployment.

If we can actually read a TokenNetwork's deposit limit then it would be better to check before calling deposit. This way we can stop a failing onchain transaction and also provide a more user-friendly message.

This should be done after upgrading to the Alderaan contracts.

Acceptance criteria

• Fail before calling the deposit function
• Show a more meaningful message

Tasks

It is very unlikely that a user runs into this.
