Using a RoundingPen as a filter doesn't work for TrueType quadratic splines (qCurveTo), because the rounding would occur too early, before these get split into atomic quadratic Bezier segments (by the superclass BasePen.qCurveTo method), thus leaving unwanted floating-point coordinates in the SVG output.
So here we add a 'ntos' parameter (by default simpli calls str()) that takes a Callable[[float], str] and can be used to customize the formatting of the numbers in SVG path coordinates.
Two small changes that significantly speed up subsetting of large fonts
such as Noto Sans CJK:
1. When emptying a charstring, simply empty its program rather than
attempting to decompile it first. (Only relevant when retaining GIDs.)
2. When reindexing charstrings, swap an accidentally-quadratic
implementation for one that is linear in the number of retained glyphs.

* Various other boring markup fixes
* Fix example indenting
* Make docstring valid RST and valid help output
* Mock import for reportlab
* It’s ok if manual links don’t appear in toctrees
* Oops typo, I guess doctests are useful
We are not doing anything about subroutines (and there shouldn’t be any
since the tables are desubroutinized), so this code is just making it
look noisy.
