v0.6.1

Added Features

• estd::detail::string is a more manageable way to pass strings around
• Experimental/partial support for AVR PGM strings: estd::v0::avr::pgm_string

Quality Updates & Bug Fixes

• estd::tuple now has conversion constructor
• estd::variant on AVR now usable, with caveats (see next section)
• String support code got a major scrub, though still a lot of crust in there
• estd::vector no longer does naughty memmove with non-trivial types

Known Issues & Limitations

• estd::is_constructible is broken on AVR. Possibly this is due to -fpermissive default flag
• estd::variant on AVR caveats:
  • Using is_convertible rather than is_constructible, for assignment
    operator, so your mileage may vary when using more exotic types and constructors
  • is_constructible being how it is may negatively affect other areas. So far unit tests are OK though.
  • move semantic seems glitchy, destructs don't seem to get called
