Replace format function in ocean.text.convert.Float

[joseph-wakeling-sociomantic]

The ocean.text.convert.Float module defines a specialized format function that writes a formatted string of a floating point number into a provided buffer. This is used under the hood in ocean.text.convert.Formatter to handle floating-point values.

However, having this separate public format definition produces a naming clash any time anyone wants to import both ocean.text.convert.Float and ocean.text.convert.Formatter (e.g. if one wants to use, say, toFloat from the former and format from the second).

It would be better to bring floating-point formatting in under the hood inside Formatter and to deprecate the function in the Float module. In this way, Formatter becomes the single point of access for formatting variables to strings, while Float can concentrate on converting text to floating-point values.

Note, downstream users of ocean.text.convert.Float.format ought to be able to use snformat (from the Formatter module) as a replacement for all their use-cases.
