Python sbp2json unconsumed 4096 refactor

[adrian-kong]

Description

Refactors sbp2json to use inbuilt handler to parse file,

• fixes the unconsumed 4096 but doesn't terminate because file doesn't get closed?
• also needs to use that iter method to manually iterate through to maintain the order
• also differs from the rust version because the float have 9 extra digits

• also differs from the rust version because the float have 9 extra digits

I think that should be expected, python only has 64 bit floats and rust has 32 and 64 so I imagine you're looking at a field that is actually supposed to be a 32 bit float
