Mono fonts not showing, no errors on invalid fonts

[SkoZombie]

When generating the document without any parameters, mono text is rendered with a proportional font:

I tried overriding the fonts in the config file:

{
  "font": {
    "baseSize": 10,
    "mono": {
      "norm": {
        "face": "/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf"
      },
      "bold": {
        "face": "/usr/share/fonts/truetype/dejavu/DejaVuSansMono-Bold.ttf"
      },
      "italic": {
        "face": "/usr/share/fonts/truetype/dejavu/DejaVuSansMono-Oblique.ttf"
      }
    }
}

However this did not make any visible difference. The config was definitely loading as it was respecting the baseSize setting.

When I set the face to an invalid font name/ path there were no errors in the console indicating it couldn't find the specified font.

I'm using Linux Mint with ApiBake 0.1.25.

Thanks for this tool! I hope more people use it as it's got a lot of promise to include in CI/CD workflows to automate documentation generation.
