Angular 13.1 support

[SebastianPodgajny]

Hi,

Do you plan to support Angular 13.1? With latest ngast version there is "Unknown import type" error

node_modules/ngast/node_modules/@angular/compiler-cli/src/ngtsc/transform/src/compilation.js:440
                finally { if (e_7) throw e_7.error; }
                                   ^

Error: Unknown import type?
