AmneziaWG 2.0: support for H1-H4 ranges

## Changes:
```
- [+] Added support for H1-H4 ranges
- [!] Fixed interface fields order (H1-H4 goes before I1-I5)
```

## Known issues:
```
- [!] no check for unique/overlap of H1-H4 values on settings apply:
  settings will be applied but wg interface will crash with "Invalid argument" error
```
