:notBefore / :notAfter

[eroux]

A few partner datasets (CBETA, 84000, etc.) have some indication of lower/upper limit dates for events (translations), while we can always indicate

  :onOrAbout "700-711"

it seems rather suboptimal, I think having

  :notBefore 700
  :notAfter 711

would be more straightforward and ease search... We would also maybe have an exact version taking an int instead of a string:

  :onExact 700

?

so you would have it that <#> :onOrAbout "7??" or <#> :onOrAbout "72?" would be replaced by

<#> :notBefore 700 ; :notAfter 799 .

and

<#> :notBefore 720 ; :notAfter 729 .

?

I think it would be nice yes
