W-5784020 (#128)

- Updated robrichards/wse-php dependency version to 2.0.3
 - Generated composer.lock again by deleting the old one and running "composer install", since the one checked-in into master requires PHP version >= 7.1 and the README.md says the required PHP Version for the PHP SDK should be >=5.6.24
 - Bumped PHP SDK patch number (1.2.0 -> 1.2.1)
 - Updated README.md file
