Indigo Toolkit is to pedantic with CXSMILES input

**Steps to Reproduce**

Indigo toolkit 1.14.0 via Java

```java
Indigo indigo = new Indigo();
indigo.loadMolecule("C1(=C(C=C(C=C1*)*)N)[N+](=O)[O-] |$;;;;;;R3;R1$|");
IndigoInchi indigoInchi = new IndigoInchi(indigo);
IndigoObject mol = indigo.loadMolecule(smi);
```

**Expected behavior**

The SMILES `C1(=C(C=C(C=C1*)*)N)[N+](=O)[O-] |$;;;;;;R3;R1$|` should be parsed without error. The compactness CXSMILES allows you omit trailing delimiters. You can confirm MarvinJS https://marvinjs-demo.chemaxon.com/latest/ does not complain on input.

**Actual behavior**

Indigo throws an error and expects the label count to equal the number of atoms:
```
C1(=C(C=C(C=C1*)*)N)[N+](=O)[O-] |$;;;;;;R3;R1;;;;$|
```

**Indigo/Bingo version**

1.14.0, 1.13.0 and others (I only tested those two).

**Additional context**

At the least a warning would be better than an error, but such inputs are unambiguous.
