Wrong file names on adjusted exports from package.json

[neo-reply-lukas]

Hello!

The package.json has wrong filenames for the built files in its exports. Leads to errors when importing fsxa-api in latest versions.

fsxa-api.esm.js --> fsxa-api.es5.js
fsxa-proxy-api.csm.js --> fsxa-proxy-api.es5.js

You can easily confirm the correct names by running npm run build in the repo and look at the files generated.
PR with the fix: #249

The mismatch
package.json:

    ".": {
      "types": "./dist/types/index.d.ts",
      "import": "./dist/fsxa-api.esm.js",
      "require": "./dist/fsxa-api.cjs.js",
      "default": "./dist/fsxa-api.cjs.js"
    }

should be

    ".": {
      "types": "./dist/types/index.d.ts",
      "import": "./dist/fsxa-api.es5.js",
      "require": "./dist/fsxa-api.cjs.js",
      "default": "./dist/fsxa-api.cjs.js"
    }

Also for proxy/package.json (but a different typo)

    ".": {
      "types": "./dist/types/index.d.ts",
      "import": "./dist/fsxa-proxy-api.csm.js",
      "require": "./dist/fsxa-proxy-api.cjs.js",
      "default": "./dist/fsxa-proxy-api.cjs.js"
    }
  },

Should be

"exports": {
    ".": {
      "types": "./dist/types/index.d.ts",
      "import": "./dist/fsxa-proxy-api.es5.js",
      "require": "./dist/fsxa-proxy-api.cjs.js",
      "default": "./dist/fsxa-proxy-api.cjs.js"
    }
  },
