bitfield rotate not working when installing from pypi

[Marco Merlin]

I find using the option "rotate: -90 " is useful when representing bitfields that are only 1 bit wide.
This works well when using the web editor, or the offline (windows) editor.

However, when using the renderer included in the pypi package, bitfield names are not rotated.
See below an example.

{ reg: [
{ name: "ADC_BM", bits: 3, attr: "rw", rotate: -90 },
{ name: "", bits: 1, attr: "r", rotate: -90 },
{ name: "ADC_ORDER", bits: 1, attr: "rw", rotate: -90 },
{ name: "DITHER_EN", bits: 1, attr: "rw", rotate: -90 },
{ name: "CHOP_EN", bits: 1, attr: "rw", rotate: -90 },
{ name: "INV_CLK", bits: 1, attr: "rw", rotate: -90 },
], config: { vspace: 200 } }
