Description:

Partition Manager v1.

Allows to resize the SPIFFS partition, or to change the global partitioning of Esp32. This means that you don't need to reflash with serial if you want to change the sizes of partitions.

How to use:

• upload partition.be or the pre-compiled partition.bec on the file system of Esp32
• in the Tasmota console type br import partition
• (or in the Berry console, type import partition)
• go the the "Consoles" page and click on "Partition Manager"

Note: this component is entirely developed in Berry code.

Note 2: added the following to webserver library:

• arg_name to enumerate web arguments and get their names
• redirect to send an HTTP redirect (code 302)
