Log Message:
Elex version 20230621
=====================

+ agcre - added internal magic numbers to agcre to attempt to catch
  misbehaving programs overwriting sections of memory (extremely coarse-
  grained checks here).
+ agcre - check internal magic numbers before attempting to execute
  regex programs
+ agcre - bump agcre magic number in the external structure
+ elex - remove striter (simple) and move to using buffer gap functions
+ elex - fix a bug whereby we check if a rule has a return value
  before attempting to parse that return value.
+ elex - fix up tests for all of these fixes
+ elex - error out when reading rules if a bad rule is encountered (as
  the resulting lexer would be erroneous if we continued)
+ elex - bump elex version to 20230621
