Function validateSpliceSites

validateSpliceSites(sequence, introns): {
    invalidIntrons: {
        intron: GenomicRegion;
        reason: string;
        sequence: string;
    }[];
    isValid: boolean;
}
Validates that introns follow GT-AG splice site consensus sequences. Checks that each intron starts with GT (donor) and ends with AG (acceptor).
Parameters
- sequence: string
  The complete gene sequence
- introns: GenomicRegion[]
  Array of intron regions to validate
Returns {
    invalidIntrons: {
        intron: GenomicRegion;
        reason: string;
        sequence: string;
    }[];
    isValid: boolean;
}
Object containing validation result and details
- invalidIntrons: {
      intron: GenomicRegion;
      reason: string;
      sequence: string;
  }[]
- isValid: boolean
Example
```
const sequence = 'ATGGTCCCAGTTAAA';
const introns = [{ start: 3, end: 11 }];
const result = validateSpliceSites(sequence, introns);
// result.isValid = true (intron sequence 'GTCCCAG' starts with GT, ends with AG)
```
