Custom symbols

The pygmt.Figure.plot method can plot individual custom symbols by passing the corresponding symbol name together with the k shortcut to the style parameter. In total 41 custom symbols are already included of which the following plot shows five exemplary ones. The symbols are shown underneath their corresponding names. For the remaining symbols see the GMT cookbook https://docs.generic-mapping-tools.org/latest/cookbook/custom-symbols.html.
