This commit converts the pdfjsdev-loader transform into a Babel plugin, to skip a AST->string->AST round-trip. Before this commit, the webpack build process was: 1. Babel parses the code 2. Babel transforms the AST 3. Babel generates the code 4. Acorn parses the code 5. pdfjsdev-loader transforms the AST 6. @javascript-obfuscator/escodegen generates the code 7. Webpack parses the file 8. Webpack concatenates the files After this commit, it is reduced to: 1. Babel parses the code 2. Babel transforms the AST 3. babel-plugin-pdfjs-preprocessor transforms the AST 4. Babel generates the code 5. Webpack parses the file 6. Webpack concatenates the files This change improves the build time by ~25% (tested on MacBook Air M2): - `gulp lib`: 3.4s to 2.6s - `gulp dist`: 36s to 29s - `gulp generic`: 5.5s to 4.0s - `gulp mozcentral`: 4.7s to 3.2s The new Babel plugin doesn't support the `saveComments` option of pdfjsdev-loader, and it just always discards comments. Even though pdfjsdev-loader supported multiple values for that option, it was effectively ignored due to `acorn` dropping comments by default.
