Feature request on NimBLEUUID

[Jeroen88]

Could you please add to NimBLEUUID.h:

    NimBLEUUID(uint32_t first, uint16_t second, uint16_t third, uint64_t fourth);

and to NimBLEUUID.cpp:

NimBLEUUID::NimBLEUUID(uint32_t first, uint16_t second, uint16_t third, uint64_t fourth) {
    m_uuid.u.type        = BLE_UUID_TYPE_128;
    memcpy(m_uuid.u128.value + 12, &first,  4);
    memcpy(m_uuid.u128.value + 10, &second, 2);
    memcpy(m_uuid.u128.value + 8,  &third,  2);
    memcpy(m_uuid.u128.value,      &fourth, 8);
    m_valueSet = true;
}

This does not save any library memory, but is does save sketch memory. In stead of

BLEUUID("ebe0ccb0-7a0a-4b0c-8a1a-6ff2997da3a6")

you can do

BLEUUID(0xebe0ccb0, 0x7a0a, 0x4b0c, 0x8a1a6ff2997da3a6)

thus trading 37 bytes of the string literal for 16 bytes uint literals, saving 21 bytes per UUID literal!

Looks good to me, could you make a PR for this?

[Jeroen88]

Maybe I will make PRs later, for now I just copied the library to my library folder and dit not set up git for it. For now it would be easy if you integrate it :)
