Coercion of incomplete floats (eg.1.)

[gislerro]

I've noticed that when iteratively parsing a json stream character by character 'incomplete' floats are 'stepped' over:

import json
import jiter

obj = {'float': 1.0}
obj_json = json.dumps(obj)

token_stream = []
sub = ''
for c in obj_json:
    sub += c
    token_stream.append(sub)

for mode in ['trailing-strings', 'on']:
    for stream in token_stream:
        parsed = jiter.from_json(stream.encode(), partial_mode=mode)
        print(f'{mode}: {stream} -> {parsed}')
    print('\n')

prints the following output:

trailing-strings: { -> {}
trailing-strings: {" -> {}
trailing-strings: {"f -> {}
trailing-strings: {"fl -> {}
trailing-strings: {"flo -> {}
trailing-strings: {"floa -> {}
trailing-strings: {"float -> {}
trailing-strings: {"float" -> {}
trailing-strings: {"float": -> {}
trailing-strings: {"float":  -> {}
trailing-strings: {"float": 1 -> {'float': 1}
trailing-strings: {"float": 1. -> {}
trailing-strings: {"float": 1.0 -> {'float': 1.0}
trailing-strings: {"float": 1.0} -> {'float': 1.0}


on: { -> {}
on: {" -> {}
on: {"f -> {}
on: {"fl -> {}
on: {"flo -> {}
on: {"floa -> {}
on: {"float -> {}
on: {"float" -> {}
on: {"float": -> {}
on: {"float":  -> {}
on: {"float": 1 -> {'float': 1}
on: {"float": 1. -> {}
on: {"float": 1.0 -> {'float': 1.0}
on: {"float": 1.0} -> {'float': 1.0}

I'd suggest to coerce 1. into the float 1.0 (or expose an option to enable that)
