Update pdoc3 requirement from ~=0.6.3 to ~=0.6.4

[dependabot-preview]

Updates the requirements on pdoc3 to permit the latest version.

Changelog

Sourced from pdoc3's changelog.

0.6.4 (2019-09-26)

• New template tunable syntax_highlighting=True that controls whether
  Highlight.js is included even if show_source_code=False.
• Fix pdoc.Class.mro() for types extending types with the same name.
• Support initializing pdoc.Module from module string.
• HTML-escape function parameter defaults so that objects' reprs don't
  break HTML.
• Other small bug fixes.

0.6.3 (2019-07-03)

• New support for LaTeX math syntax (using new config tunable latex_math=True).
• Support for running system-site-installed pdoc within a virtual environment.
• Bugfixes.

0.6.2 (2019-05-20)

• Fixes:
  • Don't generate Modules for empty namespace packages (i.e. resource directories).
  • Generate real markdown files when --output-dir is set but not --html.
  • Fix formatting of numpydoc type-only parameters.
• Auto-reload modules upon changes when in --http mode.
• New config tunable: google_analytics.
• Warn on unknown config tunables passed on the CLI.

0.6.1 (2019-05-05)

• Minor maintenance release.

0.6.0 (2019-05-03)

• New support for PEP 484 Python type annotations.
• Class __init__ methods are no longer documented separately.
  Instead, class docstring now contains __init__ method's docstring,
  and class definition line now shows __init__ parameters.
  This is in line with Sphinx / Python stdlib documentation.
• PDF docs generation via Markdown, ingestible by various
  Markdown-to-PDF converters.
• New module import mechanism with improved support for
  namespace packages.
• CLI changes:
  • New --config switch for easier setting of config.mako tunables.
  • Deprecated switches in favor of new/standard ones:
    • --overwrite → -f, --force
    • --html-dir → -o, --output-dir
    • --html-no-source, --external-links and --link-prefix are
      removed in favor of new tunables settable with --config.
  • --output-dir without --html outputs a tree of raw Markdown files.
  • The semantics of module specified as filesystem path has changed:
