* Storage: free filedata on close
* Storage: sd file read and write
* Storage: added internal storage (LittleFS)
* Storage: renamed internal commands
* Storage: seek, tell, truncate, size, sync, eof

* Storage: added raw sd-card api.
* Storage settings: work started
* Assets: use new icons approach
* Storage settings: working storage settings
* Storage: completely redesigned api, no longer sticking out FS_Api

* Storage: cli info and format commands
* Storage-cli: file list
* Storage: a simpler and more reliable api
* FatFS: slightly lighter and faster config. Also disabled reentrancy and file locking functions. They moved to a storage service.
* Storage-cli: accommodate to the new cli api.
* Storage: filesystem api is separated into internal and common api.
* Cli: added the ability to print the list of free heap blocks
* Storage: uses a list instead of an array to store the StorageFile. Rewrote api calls to use semaphores instead of thread flags.
* Storage settings: added the ability to benchmark the SD card.
* Gui module file select: uses new storage api
* Apps: removed deprecated sd_card_test application
* Args lib: support for enquoted arguments
* Dialogs: a new gui app for simple non-asynchronous apps
* Dialogs: view holder for easy single view work
* File worker: use new storage api
* IButton and lfrrfid apps: save keys to any storage
* Apps: fix ibutton and lfrfid stack, remove sd_card_test.
* SD filesystem: app removed
* File worker: fixed api pointer type
* Subghz: loading assets using the new storage api
* NFC: use the new storage api
* Dialogs: the better api for the message element
* Archive: use new storage api
* Irda: changed assest path, changed app path
* FileWorker: removed unused file_buf_cnt
* Storage: copying and renaming files now works between storages
* Storage cli: read, copy, remove, rename commands
* Archive: removed commented code
* Storage cli: write command
* Applications: add SRV_STORAGE and SRV_DIALOGS
* Internal-storage: removed
* Storage: improved api
* Storage app: changed api pointer from StorageApp to Storage
* Storage: better file_id handling
* Storage: more consistent errors
