feat: Add functions to generate secure and customizable IDs and numbers

This commit adds new functions to the '@astreak/unity' package that allow users to generate secure and customizable registration numbers, SKUs, order IDs, ticket IDs, tracking numbers, random strings, random numbers, random hex strings, random passwords, random tokens, and random IVs for encryption.

The new functions include:
- `generateRegistrationNumber(prefix: string, length: number, includeAlpha: boolean, includeNumeric: boolean): string`
- `generateSKU(prefix: string, length: number, includeAlpha: boolean, includeNumeric: boolean): string`
- `generateOrderID(prefix: string, length: number, includeAlpha: boolean, includeNumeric: boolean): string`
- `generateTicketID(prefix: string, length: number, includeAlpha: boolean, includeNumeric: boolean): string`
- `generateTrackingNumber(prefix: string, length: number, includeAlpha: boolean, includeNumeric: boolean): string`
- `generateRandomString(length: number): string`
- `generateRandomNumber(min: number, max: number): number`
- `generateRandomHex(length: number): string`
- `generateRandomPassword(length: number): string`
- `generateRandomToken(length: number): string`
- `generateRandomIV(): string`

These functions provide users with a convenient way to generate various types of secure and customizable IDs and numbers for their applications.

+Generate a secure and customizable registration number:
 
+javascript
 
-// Generate a SKU
 
+```javascript
+const registrationNumber = generateRegistrationNumber('USR', 6, true, true);
+console.log(registrationNumber); // Example output: USR-L8FJP-A1B2C3
+
+```
+
+### Generating SKU
+Generate a secure and customizable SKU:
+
+```javascript
 
+const sku = generateSKU('ELEC', 8, true, true);
+console.log(sku); // Example output: ELEC-L8FJP-A1B2C3D4
+
+```
+
+
+### Generating Order ID
+Generate a secure and customizable order ID:
+
+```javascript
+
+const orderID = generateOrderID('ORD', 6, true, true);
+console.log(orderID); // Example output: ORD-L8FJP-A1B2C3
+
+```
+
+### Generating Ticket ID
+Generate a secure and customizable ticket ID:
+
+```javascript
+const ticketID = generateTicketID('TCK', 6, true, true);
+console.log(ticketID); // Example output: TCK-L8FJP-A1B2C3
+```
 
+### Generating Tracking Number
+Generate a secure and customizable tracking number:
+
+```javascript
+const trackingNumber = generateTrackingNumber('TRK', 8, true, true);
+console.log(trackingNumber); // Example output: TRK-L8FJP-A1B2C3D4
+```
+
+### Generating Random String
+Generate a random string of a specified length:
+
+```javascript
+const randomString = generateRandomString(10);
+console.log(randomString); // Example output: a1b2c3d4e5
+```
+
+### Generating Random Number
+Generate a random number within a specified range:
+
+```javascript
+const randomNumber = generateRandomNumber(1, 100);
+console.log(randomNumber); // Example output: 42
+```
+
+### Generating Random Hex
+Generate a random hexadecimal string of a specified length:
+
+```javascript
+const randomHex = generateRandomHex(6);
+console.log(randomHex); // Example output: a1b2c3
+```
+
+### Generating Random Password
+Generate a random password of a specified length:
