Refactor constructor parameters to use a TypeScript interface for TMpesaPay

This commit refactors the constructor of the TMpesaPay class to use a TypeScript interface, providing a more concise and organized way to handle the class's properties. Instead of individual parameters, the constructor now takes a single object of type TMpesaPay. This change improves readability and maintainability of the code.

Refactor constructor parameters to use a TypeScript interface for TMpesaPay

The constructor of the TMpesaPay class has been refactored to use a TypeScript interface, providing a more concise and organized approach to handle the class's properties. The changes include converting individual parameters to a single object of type TMpesaPay. This modification enhances code readability and maintainability, making it easier to manage properties and their defaults.

Before:

constructor(
  consumerKey: string,
  consumerSecret: string,
  businessShortCode: string,
  passkey: string,
  accountReference: string,
  transactionDesc: string,
  partyA: string,
  b2cSecurityCredential: string,
  initiatorName: string,
  environment: 'sandbox' | 'live' = 'sandbox',
  transactionType: 'paybill' | 'till' = 'paybill',
)

After

constructor({
  consumerKey,
  consumerSecret,
  businessShortCode,
  passkey,
  accountReference,
  transactionDesc,
  partyA,
  b2cSecurityCredential,
  initiatorName,
  environment,
  transactionType,
}: TMpesaPay)

By utilizing an interface, this change improves the overall structure and maintainability of the code, making it easier to extend and manage the class properties in the future.
