Add a NumberedHeadingStyle option to DefaultStyles

[DynaSpan]

Hi!

At the company I work for, we use Word templates which contain normal headings (e.g. Heading 1, etc.) and numbered headings (e.g. NumberedHeading 1 etc.).

This doesn't play nice with the current implementation of numbered headings in html2openxml. If you define a numbered heading within Word, you shouldn't add the numbering properties to the heading as this will mess up the style of the heading (spacings etc.).

This PR adds a new NumberedHeadingStyle to the DefaultStyles. If the NumberedHeadingStyle is defined differently by the user than HeadingStyle, this PR will not add a numbering property to the heading, keeping the numbered heading styling intact.

This implementation ensures that current implementations keep working as-is, while opening up the styling for alternative use-cases (such as ours).

Hi @onizet,

Today I was trying to upgrade our local package to the version on nuget, 3.2.6. Unfortunately we have some issues as the NumberedHeadingStyle doesn't seem to be included in the 3.2.6 release (or our internal nuget cache is busted). Could you verify this?

Thank you!

Hello @DynaSpan , I messed up my packaging!
With Nuget, we cannot overwrite an existing package so I just published v3.2.7 with the NumberedHeadingStyle property.
Thanks for reporting
