Description
I'm debugging a Wasm compile error in a specific function. It'd be nice to be able to limit the disassembly dump to only a specific function or functions. For example:
wasm-objdump -d out.wasm --functions=13,64
This would only show the disassembly for functions 13 and 64. For bonus points, it'd be nice to be able to specify their name if a names section is present.

Research direction
Start at the wasm-objdump disassembly option handling and trace how function selection is currently processed. Add a way to select multiple functions by index, with optional names-section lookup, and verify that disassembly output is limited to the requested functions.
