i2c driver for Tasmota to get voltage input

I am looking to interface a MCP3021 based sensor that goes from 0-5v, and the SFM3000 with Tasmota. A general purpose i2c driver that uses the Wire library to read voltage values from an i2c address would work just fine, as the post-processing can then be done elsewhere. To clarify, the only thing that is being looked for is a general purpose i2c driver that reads voltage outputs from the MCP3021 and SFM3000, and other i2c devices following the Tasmota format so it can be enabled at compile and used. Please provide ETAs, I don't think this should take long for someone with the prerequisite knowledge.
