jsrrdgraph: Performance fix
commit 2a74a333ff143499b465234f0395a4aad7bdaa78 ("Upgrade to
javascriptrrd ver 1.1.1") converted getByteAt calls to a getEndianByteAt
call, but this also introduced a branch operation. Since endianess is
dependent on the file, we can move the switch_endian check outside the
function.
Performance improved from 0.148ms (n=336k) to .039ms (n=384k) which
translates to about 30 seconds!
