memory leaks fixed

[VasiliyTurchenko]

Hi! I have noticed that a number of possible memory leaks may happen in the project. I fixed that, mostly using std::shared_ptr instead of raw pointers. It adds tiny overhead but automates memory deallocation at scope exit.

Also I have added

enum class chipType : uint8_t {chipTypeSPI = 0U,
                                   chipType25EE,
                                   chipType93EE,
                                   chipType24EE,
                                   chipType95EE};

instead of anonymous numbers to ease control flow management in the program.

• added .gitignore to prevent some Qt and CMake local files gettinig into the repo.

Hello! It's a good job! But you are not selecting the chip type correctly: 0- SPI (25xx) 1- i2c (24xx) 2- Microwire (93xx) 3- 25xxx is not used today (SPI but not NOR) 4- 95xxx Please split these changes into multiple pull requests. It will be easier for us to work that way.

The memory leak you fixed in dialogsfdp.cpp is also present in mainwindow.cpp.

Oops.. I was mislead by this line:

QVector <QString> chType = {"SPI_FLASH","25_EEPROM","93_EEPROM","24_EEPROM","95_EEPROM"};

It seems that chType strings order is not the same as chipType numbers. Actually this QVector <QString> chType in mainwindow.h is unused and can be deleted.
