Expressions / introduce the match operator
...
This operator allows mapping from input values to output values of different
kinds and handles variable arguments count.

Expressions / add utilities for using strings in GLSL & more type checking
...
It is now possible to specify a type hint when parsing an expression, which
helps determine the output value type.
When no single output type can be inferred, an error is thrown.
For strings, every literal value will be replaced by a number and a map of
these associations will be kept in the parsing context, which is passed
recursively.

Converting expressions to GLSL is now done in ol/style/expressions, with the
same logic as before in ol/webgl/ShaderBuilder.
