Add token command

[dominicletz]

Example:

> diode token
[INFO] Diode Client version : v0.4.x
[INFO] Client address       : 0xxxxxxxxxxxxxxxxxxxxx 
[INFO] Fleet address        : 0xxxxxxxxxxxxxxxxxxxxx 

[INFO] Token                : DIO 
[INFO] Balance              : 10 DIO 

> diode token -send 10dio -to my_mom.diode
[INFO] Diode Client version : v0.4.x
[INFO] Client address       : 0xxxxxxxxxxxxxxxxxxxxx 
[INFO] Fleet address        : 0xxxxxxxxxxxxxxxxxxxxx 

[INFO] Sending              : 10 DIO to 0x34234289402
[INFO] Transaction Hash     : 0x45353485032 

The task is to create a new command to check token balance and to send tokens through the diode network. You must specify:

• The amount
• The destination
• The unit

Unit	Wei Value	Wei
wei	1 wei	1
kwei	1e3 wei	1,000
mwei	1e6 wei	1,000,000
gwei	1e9 wei	1,000,000,000
microether (microdiode)	1e12 wei	1,000,000,000,000
milliether (millidiode)	1e15 wei	1,000,000,000,000,000
ether (diode)	1e18 wei	1,000,000,000,000,000,000

Optional features might be:

• Providing a gas fee
• Specify a ERC20 contract token instead
• etc...
