Hello and thanks for the project, I appreciate clean C over bulky Arduinish code.
This pull request brings two additional options to the SD/MMC peripheral and fixes a bug when the static IP option is selected (ip_info was undeclared; a typo).
The first SD/MMC option allows the users to select either 1-line or 4-line width slot mode. This is crucial for ESP boards like TTGO T8 where three other data pins of an SD card slot are not connected.
The second SD/MMC option allows the users to select the SD/MMC max frequency to operate on.
The latter option, however, has not influenced the final transmission speed, which remained around only 30 KB/s. At the same time, I've achieved ~300 KB/s speed using https://github.com/fa1ke5/ESP32_FTPServer_SD_MMC project. Don't know why. Maybe you have ideas.
Anyway, I've just decided to put in my two cents in your project.
