\oslash documentation is wrong

[eschnett]

The documentation for \oslash reads:

Sandwich product: ω⊘η = (~ω)⊖η⊖ω

However, it seems to implement η⊘ω instead (with arguments commuted):

julia> R = exp(π/4*v12)
0.7071067811865476 + 0.7071067811865475v₁₂

julia> (~R) ⊖ v1 ⊖ R
0.0 + 2.220446049250313e-16v₁ + 1.0v₂

julia> R ⊘ v1
-0.7071067811865476 + 0.7071067811865475v₁₂

julia> v1 ⊘ R
0.0 + 2.220446049250313e-16v₁ + 1.0v₂

Note that ⊘ is a new symbol definition which has not quite existed before I defined it. Most literature uses the >>> definition instead, which I think is slightly wrong as a definition.
