Submit string as datapoint...

Hi... I am interested in ergo and oracle pools concept...I am trying to launch an oracle pool on my local ergo testnet, but I need to submit different data types as datapoint other than just numbers(f64)...
I want to ask is there any specific reason that this version of oracle-core and connector works with just numbers (f64 or u64) as datapoint?...
I changed all datapoint related data types( u64 and f64) to str and modified connector and oracle-core modules in connector project and now I`m trying to change deviation checks in oracle-core/api.rs now, but I doubted if there is any logical obstacle in my way...
Thanks in advance for your help...

Start by reviewing oracle-core/api.rs and the datapoint-related changes described for the connector and oracle-core modules. Trace where deviation checks assume numeric f64 or u64 values, then determine the scope and compatibility requirements for supporting string datapoints. Done would require an agreed design and corresponding updates across the affected modules.
