Cope with behavior change in newtxtext v1.738

Recently, newtxtext's behavior of sans-serif font setting has become
unstable and the option helvratio stopped working as of newtxtext
v1.738.

As a workaround, load tgheros.sty provided by the tex-gyre package
before loading newtxtext with the same scaling facter which works
with previous versions of newtxtext.

Do similar changes in pstricks figures under SMPdesign/ which use
sans-serif font only.

Note:
newtxtext's main feature is to provide improved Times Roman clone based
on TeX Gyre Termes.  The author of newtxtext doesn't pay much attention
on sans-serif font behavior, it seems, and has made v1.738 and later
respect default sans-serif font at the time of loading newtxtext.sty.

Changelog in newtx's README [1] reads:

Changes in version 1.738
1. Documentation updated for newtx.sty usage.
2. Modified newtx.sty and newtxtext.sty to ensure that default effects
   of \mathsf and \mathtt are the same in both cases, and to ensure that
   in both, the prior loading of a sf or tt text font would result in
   those being used for \mathsf, \mathtt without any further interventions.
