Add a new layout (US, Symbolic)

Layout based on the default us keyboard map, edited for scientific literature.
Layer 3 (AltGr) is used to access Greek letters and common scientific symbols.
Added simple Greek letters to alphas, and common symbols everywhere else.
TLDE and BKSL are AltGr-inverse, to facilitate placement of ESC over TLDE on
60% keyboards. LGST (Iso Key) contains rarely used floor and ceiling brackets.
