v0.2.0

BREAKING: update rand_core dep to latest v0.9
POSSIBLY BREAKING: the seed is now printed to stderr instead of stdout
Replace dependency on hex with better-maintained const-hex v1
Add optional feature rand-v09: when it's enabled, library re-exports rand v0.9 that will be accessible as rand_dev::rand
Improve CI workflow

See #4

v0.1.1

Add DevRng::fork method that derives a new randomness generator from existing one
May be useful when you have several threads/futures/places where you need access the randomness generation, but you don't want to mess with ownership system.
Changes format of seed printed to stdout
Old format:
```
Tests seed: {seed}
```
New format:
```
RUST_TESTS_SEED={seed}
```
New format makes it easier to copy-paste env var when you want to reproduce the tests.
Add Github Actions
