Feature-Ammeter Circuit Symbol Request

[MorXMann]

Is it possible to include an option to incorporate the circuit symbol for an ammeter into the simulation, according to the IEC 60617 standard (an 'A' inside a circle)?

For some laboratory exercises, it’s necessary to indicate that an ammeter must be placed in the actual circuit; in this case, the circle symbol is more explicit than the arrow.

Similar solution to https://github.com/sharpie7/circuitjs1/issues/857 but applied to Ammeter.

Thank you in advance and for the great project you have created, which is invaluable for teaching.
