Regex in isFriendly should be anchored

[kolpav]

I think I found few issues with addresses.

1. regex in isFriendly should be anchored otherwise it returns true for invalid addresses
   parse fails as it should, problem is isFriendly not parseFriendly
2. addresses for which parseRaw throws should also return false from isRaw
3. addresses for which parseFriendly throws should also return false from isFriendly

You can verify by using my tests without change in isFriendly and see that address !@#$%^&*AAAAAAAAAAAAAA AAAAAAAAAA AAAAAAAAAAAA A is considered to be friendly:

 FAIL  src/address/Address.spec.ts
  Address
    ✓ should parse addresses in various forms (3 ms)
    ✓ should serialize to friendly form
    ✓ should implement equals
    ✕ should throw if address is invalid (8 ms)

  ● Address › should throw if address is invalid

    expect(received).toBe(expected) // Object.is equality

    Expected: false
    Received: true

      94 |             Address.parseFriendly('!@#$%^&*AAAAAAAAAAAAAA AAAAAAAAAA AAAAAAAAAAAA A')
      95 |         }).toThrowError('Unknown address type');
    > 96 |         expect(Address.isFriendly('!@#$%^&*AAAAAAAAAAAAAA AAAAAAAAAA AAAAAAAAAAAA A')).toBe(false)
