bug(slp1_roman): Invalid virtual key sequences in stores

[mcdurdin]

This is not valid .kmn syntax. [...] is treated as a virtual key, so this will not be doing what you expect. In Keyman Developer 18, these are detected as invalid, because they are not valid key codes:

slp1_roman.kpj - info KM05002: Building release/s/slp1_roman/slp1_roman.kpj
slp1_roman.kmn - info KM05002: Building release/s/slp1_roman/source/slp1_roman.kmn
slp1_roman.kmn:76 - error KM0200A: Invalid token found
slp1_roman.kmn - info KM05007: release/s/slp1_roman/source/slp1_roman.kmn failed to build.
slp1_roman.kpj - info KM0500C: Project release/s/slp1_roman/slp1_roman.kpj failed to build.

@Harshavardhan-Pandurangan Please note the issue above for the slp_roman` keyboard. When I approved your keyboard I only checked that your keyboard would build, and it did build in Keyman Developer 17.0 but I think Keyman Developer 18.0 is being more rigorous in checking.

So, these two store don't actually function as you are hoping:

store(vowels) U+0061 [U+0061 U+0304] U+0069 [U+0069 U+0304] U+0075 [U+0075 U+0304] [U+0072 U+0325] [U+0072 U+0325 U+0304] [U+006C U+0325] [U+006C U+0325 U+0304] U+0065 [U+0061 U+0069] U+006F [U+0061 U+0075]
store(consonants) U+006B [U+006B U+0068] U+0067 [U+0067 U+0068] U+0063 [U+0063 U+0068] U+006A [U+006A U+0068] [U+0074 U+0323] [U+0074 U+0323 U+0068] [U+0064 U+0323] [U+0064 U+0323 U+0068] U+0074 [U+0074 U+0068] U+0064 [U+0064 U+0068] U+0070 [U+0070 U+0068] U+0062 [U+0062 U+0068] U+0079 U+006C U+0076 U+0068

You would need to remove all the "grouped" ones like [U+0061 U+0304] because Keyman stores won't treat those as a unit. I can't see that removing those "grouped" ones would be detrimental to how your keyboard works, because you've written extensive rules below that seem to already produce the behavior you want.
