Adds 4D matrix to Dyon.
Uses column major as internal format, but syntactically row major is
used for easier working with basis vectors.
Uses `;` to separate between basis vectors.
Parentheses around vectors can be omitted inside the `mat4` brackets.
Supports vector swizzling with matrices. To distinguish between vector
and scalar swizzling when omitting parentheses, one must add a trailing
`,`, e.g. `mat4 {xy (1, 2),;}`.
