Math: implement m:m matrix converter (community)

[caio-pizzol]

What

Implement the m:m (matrix) OMML → MathML converter.

OMML: m:m → m:mPr (column count, justification, spacing) + m:mr rows, each with m:e cells
MathML: with rows and `` cells
Spec: §22.1.2.60
Difficulty: Hard

Details

• m:mPr/m:mcs/m:mc/m:mcPr/m:count@m:val — column count
• m:mPr/m:mcs/m:mc/m:mcPr/m:mcJc@m:val — column justification
• m:mr — matrix row, contains m:e elements (one per cell)
• Often wrapped in m:d (delimiter) for brackets: [matrix]

How to implement

1. Create converters/matrix.ts
2. Iterate m:mr rows → <mtr>, each m:e → <mtd>
3. Register as 'm:m': convertMatrix
