files: check offsets and split copy's with same name

[IamPete1]

Currently the file parsing does not check the offset, this means that is does not spot missed data and it will concatenate multiple copys into single file. This uses the offset to start a new file. Currently it just appends _Vx to the file name for copies. This is a bit clunky but is a none breaking change. In the future we might want to return a array for each file so the tool can decide how to present the multiple copy's (I was thinking of a drop down selection).

Currently we get this:

With this patch:

Using @SYS/uarts.txt as a example. We currently get:

This does do a file compare, so you will only get a new version if it is different.
