MOAC v2.0.2

This release was done mostly to prepare for building some distro
packages.

Library: introduced new function charsets.IsDefault()

When running "make install" it's now possible to exclude binaries during
installation, which can make things easier during packaging.

Testing now supports testing CLI programs via "testscript" from
go-internals.

Rohan Kumar (11):
      Refactor: consistency across cmd/* parseOpts()
      Chore(lint): update golangci config for cli tests
      Test: introduce CLI tests for cmd/moac
      Test: introduce CLI tests for cmd/moac-pwgen
      Refactor: make cmd/*/main.go only exit in main()
      Feat: new function charsets.IsDefault()
      Refactor: simplify charsets.ParseCharsets
      Refactor: simplify genpw_test.go
      Build: allow excluding bins in "make install"
      Chore(dep): bump deps, date
      Chore(CI): update CI configs

MOAC v2.0.0

This is a major release with many breaking changes to the library, but
hardly any visible changes to the CLI programs.

Changes common to both the CLI and library:

- Entropy estimates are slightly more accurage
- While normal non-CGO performance is about the same, perf with msan or
  race-detectors enabled is much slower. This should only be visible
  when generating/analyzing hundreds/thousands of passwords.

Changes to the "moac" and "moac-pwgen" CLI programs:

- Input validation: impossible physical values (including temperatures
  above the Planck Temperature) are forbidden.

Changes to the library:

v2.0.0 is close to a full re-write. So many APIs have changed for v2 that listing all the changes would be only slightly shorter and harder to follow than just reading the updated docs.

- A new "charsets" subpackage defines a Charset interface, CustomCharset
  and DefaultCharset implementations, and a CharsetCollection. The
  CharsetCollection's Add() method now handles all redundancies.
- Input validation
- Replace exported functions accepting a "quantum" bool with quantum and
  non-quantum variants of those functions.
- Password reqs are passed as a struct to GenPW
- pwgen.BuildCharsets is now charsets.ParseCharsets
- Parameters and returns for almost every function have changed

MOAC v1.2.0

- More accurate entropy estimations with some charset de-deuplication
- The library now has the BuildCharsets func exported
- Add reproducible builds
- CLI programs now sanitize unwanted characters in custom charsets

This should be the last minor 1.x release; development will now shift
towards v2.0.0, with occasional patches to 1.2 if necessary.
