_parse_nh_struct parsed the sum field with int(), so a native histogram
whose sum is not integral failed to parse with
ValueError: invalid literal for int() with base 10: '100.5'
NativeHistogram.sum_value is a float and the OpenMetrics writer emits the
sum verbatim (e.g. sum:100.5), so the library could not parse its own
output for the common case of a non-integer sum. Parse sum with float()
to match; count, schema and zero_count remain int as they are genuinely
integers.
Add test_native_histogram_float_sum, which parses a native histogram
with a fractional sum and checks it round-trips to sum_value 100.5.
