+- Adjusted `lf cmdread` to respond to client when complete and the client will then automatically call `data samples`
 - Improved backdoor detection missbehaving magic s50/1k tag (Fl0-0)
 - Deleted wipe functionality from `hf mf csetuid` (Merlok)
 - Changed `hf mf nested` logic (Merlok)

 ### Added
+- Added a bitbang mode to `lf cmdread` if delay is 0 the cmd bits turn off and on the antenna with 0 and 1 respectively (marshmellow)
 - Added PAC/Stanley detection to lf search (marshmellow)
 - Added lf pac demod and lf pac read - extracts the raw blocks from a PAC/Stanley tag (marshmellow)

 - Added to `hf emv exec` MSD path for VISA and Mastercard and some other compatible EMV cards (Merlok)
 - Added to `hf emv exec` SDA, DDA, fast DDA, CDA calculations for VISA and Mastercard and some other compatible EMV cards (Merlok)
 - Added `hf emv test` - crypto tests for DES, AES, SHA, RSA, SDA, DDA, CDA and some other crypto functions (Merlok)
