Feature request: Make argument order configurable

[LhKipp]

Hi jfecher,

thank you for creating this nice testing utility (and documenting it well 💯 👍🏻 ). I enjoy using it.

There is one thing I would like to have: I am currently using the feature to add arguments to the called binary via the args keyword. Here is an example test of mine:

lda #$2
sta $0
lsr $0

; args: 0 1
; expected stdout:
; pc   |sp |a  |x  |y  |C|Z|I|D|B|O|N
; 6    |0  |2  |0  |0  |0|0|0|0|0|0|0
; 
; 0000:   01

The arguments I manually specify are always added before the test file. Would it be possible to make that configurable? For example with a special argument <input-file>, that is substituted with the input-file by golden-tests. E.G. the args line in my example would become ; args: <input-file> 0 1.

If this suggestion is accepted, I can implement it :)
