TypeError "aws_xray_sdk_mysql_1.captureMySQL is not a function"

We've recently updated `aws-xray-sdk-mysql` from version `3.2.0` to `3.3.3`, but experienced issues with our Typescript projects.

Due to the changed Typescript definitions, we had to adjust the import from
```typescript
import captureMySQL from 'aws-xray-sdk-mysql';
```

to

```typescript
import {captureMySQL} from 'aws-xray-sdk-mysql';
```

However, this resulted in errors as such:
```log
{
"errorType": "TypeError",
"errorMessage": "aws_xray_sdk_mysql_1.captureMySQL is not a function",
"stack": [
"TypeError: aws_xray_sdk_mysql_1.captureMySQL is not a function",

]
}
```

**Workaround**

As a temporary workaround, replace

```typescript
import {captureMySQL} from 'aws-xray-sdk-mysql';
```

With

```typescript
// eslint-disable-next-line @typescript-eslint/no-var-requires
const captureMySQL = require('aws-xray-sdk-mysql');
```
