Enhancement: Add native MOS support for a TYPE command about agon-mos

[breakintoprogram]

Going to mark this as 'Won't Do' as the functionality is already provided by the 'more' command and is always available (if the more binary is copied into the MOS folder) by using the *more command from MOS or BBC BASIC.

I'm wondering, in general, if a more straightforward distribution channel for obtaining MOS utility programs is needed, especially for new Agon owners, to spare them from having to hunt down additional MOS commands, which are more core-essential than optional. For example, I don't believe any of the AgonLight hardware retail channels provide instructions or a link to obtain a bundling of these commands. If these commands could be compiled into a bundle and be included with (or linked to) each corresponding MOS release, that would be helpful. The retail outlets which offer pre-configured microSD cards would likely appreciate these utilities being part of some official MOS add-on bundle, as well. Just a thought.
