Math: implement m:func function apply converter (community)

[caio-pizzol]

What

Implement the m:func (function apply) OMML → MathML converter. Used for named functions like sin, cos, log applied to an argument.

OMML: m:func → m:funcPr + m:fName (function name) + m:e (argument)
MathML: sin⁡argument
Spec: §22.1.2.39
Difficulty: Medium

Details

• m:fName contains m:r runs with the function name (e.g. "sin", "cos", "log")
• The invisible function application operator ⁡ (U+2061) separates name from argument
• Function names should use mathvariant="normal" (upright, not italic)

How to implement

1. Create converters/function.ts
2. Convert m:fName children, then append <mo>⁡</mo>, then convert m:e
3. Register as 'm:func': convertFunction
