250 migrate zenroom script usage within planetmint so that tx schema 21 is used (#253)

Browse Source 
* * **Changed** adjusted to zenroom calling convention of PRP #13 (breaking change)
* **Changed** zenroom test cases to comply to the new calling convention
* **Fixed** zenroom signing bug (call of wrong function)
* **Changed** using cryptoconditions 0.10.0
* **Deprecated** usage of ripde160md as a address generation algorithm, isn't available from python 3.9.14 on, skipping these tests from now on.
* **Changed** script/ouptut tag to be of type array or object for schema v3.0 and v2.0
* **Changed** added 'script' handling to the common/transactions.py class
* **Fixed** data input handling to the transaction fullfillment methods
